1.0 INTRODUCTION 1.1 PERMIT HISTORY Discharges to the Boston Water and Sewer Commission s (Commission) separate storm drainage system are regulated under the U.S. Environmental Protection Agency s (EPA) National Pollutant Discharge Elimination System (NPDES) Stormwater Permit Regulations. The Commission s NPDES Stormwater Permit (MAS010001) was issued by the EPA and the Massachusetts Department of Environmental Protection (DEP) on September 29, 1999, and became effective on October 29, 1999. The five year permit expired on October 29, 2004, but its terms remain in effect until a new permit is issued. The Commission s 2003 Stormwater Management Report, which was submitted to the EPA on February 27, 2004, constituted the Commission s reapplication for an NPDES Stormwater Permit. In August 2012, the Commission entered into a Consent Decree following two years of negotiations with the U.S. Environmental Protection Agency, U.S. Department of Justice and the Conservation Law Foundation (CLF) regarding discharges of pollutants from the Commission s municipal separate stormwater system (MS4) and wastewater collection system. The Consent Decree, lodged in the U.S. District Court on August 23, 2012, outlines a series of short-term and long-term remedial measures that the Commission will implement to further its compliance with its existing NPDES permit and the Clean Water Act. They include enhancements to the Commission s Illicit Discharge Detection and Elimination and Capacity, Management Operation and Maintenance (CMOM) Programs; expansion of the Commission s stormwater related public education and outreach activities; requirements for developing and implementing Green Infrastructure and Stormwater Best Management Projects within the City; updating the Commission s stormwater model; executing intergovernmental agreements with various state and local agencies; improvements to the tracking and reporting of sewer system overflows and development of an SSO Emergency Response Plan; and development of programs to inspect Construction Sites and Industrial Facilities, to confirm that they are in compliance with the terms of their own NPDES Stormwater Permits. 1.2 ANNUAL REPORT REQUIREMENTS In accordance with the NPDES Stormwater Permit (the Permit), the Commission is required to report annually to the EPA and the DEP regarding the status of its pollution prevention and stormwater management programs. This report provides a summary of the stormwater activities undertaken by the Commission in 2012. Provided herein are descriptions of the Commission s outfall monitoring and illicit discharge remediation

programs, stormwater related enforcement actions, discussions regarding modifications to these programs, annual expenditures, water quality improvements and an assessment of structural controls. Many of the programs, plans and activities described in this report are required under the Consent Decree. Separate Consent Decree compliance reports are being submitted to EPA, the U.S. Department of Justice, DEP and the CLF on a semi-annual basis. Many of the deadlines for submittals of reports, plans and implementation of programs required under the Consent Decree occur after the end of 2012. If relevant, they will be reported on in future annual Stormwater Management Reports as they occur. 1.3 COMMISSION JURISDICTION AND LEGAL AUTHORITY FOR DRAINAGE SYSTEM AND STORMWATER MANAGEMENT The Commission was created pursuant to an act of the Massachusetts Legislature under Chapter 436 of the Acts of 1977 as a political subdivision of the Commonwealth, separate and apart from the City of Boston. The enabling act charged the Commission with the responsibility for the operation and maintenance of the water distribution system and the wastewater collection and stormwater drainage systems which serve the City of Boston. Through its enabling legislation the Commission is empowered to promulgate rules and regulations in order to perform its statutory functions and duties. The Commission s Regulations Governing the Use of Sanitary and Combined Sewers and Storm Drains and Requirements for Site Plans are briefly described below. Copies of the documents are available by contacting the Commission and a downloadable version is available from the Commission s web site located at www.bwsc.org. Pursuant to the Consent Decree, the Commission will be exercising greater authority over stormwater discharges originating from construction sites and industrial facilities. These programs are discussed further in Section 3. Sewer Use Regulations: The majority of the Commission s stormwater management controls are enforced through its Regulations Governing the Use of Sanitary and Combined Sewers and Storm Drains (the Sewer Use Regulations). The Sewer Use Regulations were adopted in 1983 and amended in 1989. They were amended again in 1998 to strengthen and clarify the requirements, particularly as they pertain to stormwater discharges. In 1998, the Commission also amended its Penalty Schedule by adding and increasing the fines for several Sewer Use Regulation violations. General Service Applications and Requirements for Site Plans: The Commission requires that a General Service Application and a site plan be submitted for every new or reconstructed water, sewer, or storm drain service connection. The Requirements for Site Plans are to assist developers, builders, architects, engineers, and others in preparing site plans that conform to the Commission s Sewer Use Regulations and to help them secure the necessary approvals from the Commission. 1-2

The site plan must be approved by the Commission s Chief Engineer before construction may begin, and it will not be approved unless it complies with the Commission s Requirements for Site Plans and Sewer Use Regulations. The site plan review provides an opportunity to review the components of the project and condition the approval on compliance with the Commission s Sewer Use Regulations, Requirements for Site Plans, and other requirements. The Commission s Requirements for Site Plans are updated as needed, generally about once a year. In accordance with Section VII, Part K of the Consent Decree, the Commission revised its Requirements for Site Plans to require developers of Construction Sites (Over 1 acre or plan to disturb more than 1 acre) to apply for a Notice of Intent with EPA for a Construction General Permit and also require the submission of a Stormwater Pollution Prevention Plan (SWPPP), which will be summarily reviewed by the Commission with the site plan application. 1.4 STORM DRAINS OWNED, AND STORMWATER ACTIVITIES PERFORMED BY OTHERS The Commission controls most of the municipal storm drains in Boston. However, some storm drains and outfalls are owned by other city agencies. For example, drains and outfalls located in the Marine Industrial Park in South Boston are owned and operated jointly by the Economic Development and Industrial Corporation of Boston; the Boston Parks Department owns drains in Franklin Park and Boston Common, and in other city parks. Other storm drains and outfalls in the city are owned by state agencies, such as the Massachusetts Department of Transportation and the Department of Conservation and Recreation; these drains and outfalls are not controlled by the Commission. In several locations Commission owned storm drains interconnect with those owned by the Town of Brookline, Town of Dedham, Town of Milton and City of Newton. The Commission does not have jurisdiction or control over the discharges from these municipalities, nor does it have jurisdiction and/or control over roadways, roadway maintenance, city parks or city or state facilities which may impact the Commission s separate storm system. Further, the Commission does not manage or control some of the stormwater programs and activities required under its NPDES. For example, the Household Hazardous Waste Collection Program is currently managed by the Boston Public Works Department. To help address jurisdictional issues, and in compliance with terms of the Consent Decree, in 2012, the Commission began establishing Memorandums of Understanding (MOUs) with other City of Boston Departments and Authorities, other municipalities, and with state agencies. As of the end of 2012, the Commission had executed MOUs with the Boston Public Works Department, the Boston Parks and Recreation Department, the Boston Inspectional Services Department, the Brookline Department of Public Works and the Town Dedham. 1-3

1.5 CHARACTERIZATION OF SEPARATED SUB-CATCHMENT AREAS The Commission s storm drain outfalls are listed in Table 1-1. There are currently 203 storm drain outfalls in the Commission s drainage system. Of those, 99 are classified as major outfalls, and 104 are classified as non-major outfalls. Table 1-2 lists locations where Commission owned storm drains interconnect with (discharge to) storm drains owned by others. There are currently 19 interconnection locations. Under the Consent Decree the Commission now must field screen combined sewer overflow outfalls during wet and dry weather. Table 1-3 lists the Commission s 30 combined sewer overflow outfalls. 1.6 MAPPING OF SUB-CATCHMENT AREAS AND OUTFALL LOCATIONS The map (Figure 1 in Appendix A) shows the locations of the Commission s storm drain outfalls and combined sewer overflow (CSO) outfalls. The locations of the interconnections will be added to the map in 2013. The sub-catchment areas tributary to the storm drain outfalls and interconnections are also shown. 1-4

2.0 FIELD SCREENING, SUB-CATCHMENT AREA INVESTIGATIONS AND ILLICIT DISCHARGE REMEDIATION Under the terms of the Consent Decree the Commission is required to: annually perform wet and dry weather field screening of its storm drain outfalls, CSO outfalls and manholes interconnecting with other MS4 drain systems; implement a sub-catchment area screening program; establish priorities and a schedule for investigating subcatchment areas that demonstrate contamination; and, correct or repair illicit discharges within deadlines established in the Consent Decree. The Commission performed ongoing illicit discharge investigations and elimination prior to entry of the Consent Decree in 2012, and will continue doing so under the established guidelines. 2.1 FIELD SCREENING AND SUB-CATCHMENT AREA PRIORITIZATION Specifically as required under the Consent Decree, the Commission has completed, or is taking the following actions: By May 31, 2013, under dry-weather conditions (less than 0.1 inches of rain in the preceding 48 hours and no significant snowmelt), the BWSC shall inspect all MS4 outfalls, MS4 discharges to other municipalities MS4s or non-bwsc outfalls, and CSO outfalls, and sample those with flow. By May 31, 2013, at least once during wet weather conditions, the BWSC shall sample all MS4 outfalls, MS4 discharges to other municipalities MS4s or non- BWSC outfalls, and CSO outfalls where flow was not observed during dry weather inspections or sampling, as well as those outfalls or interconnections that did not equal or exceed IDDE screening thresholds during dry-weather sampling. Within 90 days of lodging of the Consent Decree, the BWSC shall submit to EPA for review and Approval and to CLF and MassDEP: a. A revised priority ranking of all sub-catchment areas based on all information and data available; b. An MS4 and CSO sub-catchment area map showing the revised ranking of each sub-catchment area; c. A schedule for completion of all sub-catchment area investigations which shall provide that: 2-1

i. Investigations of all sub-catchment areas discharging to, or near, Constitution Beach will be completed within 12 months of lodging of the Consent Decree; ii. Investigations of all sub-catchment areas discharging to, or near, Malibu and Tenean Beaches will be completed within 24 months of lodging of the Consent Decree; and iii. Investigations of all sub-catchment areas discharging from the BWSC system will be conducted according to the BWSC s priority ranking order and will be completed within seven (7) years of lodging of the Consent Decree as follows: a) 35% of the sub-catchment area investigations to be completed within three (3) years of lodging of the Consent Decree; b) another 35% of the sub-catchment area investigations to be completed within six (6) years of lodging of the Consent Decree; c) the balance of the sub-catchment area investigations to be completed within seven (7) years of lodging of the Consent Decree; The BWSC shall complete its sub-catchment area investigations in accordance with the priority ranking schedule. By January 31 st of each calendar year, the BWSC shall revise its priority ranking of sub-catchment areas to be investigated to: a. include all sub-catchment areas newly identified as needing investigation based on evidence of discharges contaminated by human waste; and b. Adjust priorities based on new evidence. On November 21, 2012, the Commission submitted to EPA, DEP and CLF the first required Sub-catchment Prioritization and Schedule for Completion of Investigations report ( Priority Report ). At that point in time only dry weather field screening of most of the storm drain outfalls and interconnections had been completed. The Priority Report described the protocols used for collecting the screening data; the methodology for prioritizing sub-catchment areas for investigation; the priority ranking of the subcatchments which resulted; and, a schedule for completing sub-catchment area investigations within the seven year time line established by the Consent Decree. On January 30, 2013, as required by the Consent Decree, the Commission submitted a revised Sub-catchment Prioritization and Schedule for Completion of Investigations 2-2

report (Revised Priority Report). 1 The content of the Revised Priority Report was similar to the November report; however, it included both wet and dry weather field screening data collected as of December 2012, for storm drain outfalls, interconnections and CSO outfalls. The full Revised Priority Report, including the priority ranking and schedule, is provided in Appendix C. The outfall screening data collected in 2012 and used for the Revised Priority Ranking is provided in Table 2-1 (dry) and Table 2-2 (wet). A discussion of the procedures and protocols used for collecting the screening data is included in the Revised Priority Report. 2.2 ILLICIT DISCHARGE DETECTION AND ELIMINATION PLAN Under the Consent Decree the Commission was required to submit to EPA, DEP and CLF a revised Illicit Discharge Detection and Elimination Plan (IDDE Plan). The IDDE Plan detailed and updated the Commission s top-down approach, including modifications as appropriate to address investigations of CSO outfalls. It described the investigation methods and analytical techniques that the Commission employs to locate and verify illicit discharges, and methods by which sources of illicit discharges would be removed. The IDDE Plan was submitted to EPA, DEP and CLF on December 18, 2012. The full IDDE Plan is provided in Appendix D. In general, illicit discharge investigations are performed by Commission consultants, as well as by in-house staff. The contracts for investigations performed by consultants are described further below. Routine reports of suspected illegal sanitary connections are usually directed to the Commission s Field Engineering Division. Field Engineering is currently comprised of the Director of Engineering Services, Deputy Director of Engineering Services, a Manager of Field Engineering, a Systems Engineer, and five (5) Field Service Engineers, plus seven (7) day-shift crews, which includes one (1) Saturday crew. In 2012, a Field Engineer and two Field Engineering crews spent about 15 percent of their time investigating illegal sanitary connections. Illegal connection related work performed by Field Engineering staff in 2012 focused on performing targeted investigations and providing field support to the Commission s consultant for the Citywide Illegal Connection Investigation Phase 3 program (CWI3), which is described below. The methodology for investigations performed by Field Engineering vary, but usually consist of manhole inspections, dye testing of buildings, video inspections of pipes, and occasionally sandbagging of manholes. Field Engineering staff also respond to hazardous materials spills and illegal dumping complaints, including initial response, investigation, coordination with other agencies, enforcement and cleanup where applicable. 1 Although the Revised Priority Report was submitted after the period covered by the 2012 Stormwater Management Report it is discussed herein because it provides the basis upon which investigations in 2013 will be prioritized. 2-3

2.3 ILLEGAL CONNECTION INVESTIGATION CONTRACTS Since 1999, the Commission has executed four contracts to have consultants perform illicit discharge investigations of the Commission s drainage system. The Stony Brook Illegal Connection Investigation (SBI) Program was carried out between 1999 and 2005, at a cost of $1,478,709, plus $57,388 for police details. The Citywide Illegal Connection Investigation (CWI) Program overlapped with the SBI, and was carried out between 2004 and 2009. Total cost for the CWI program was $1,536,000, plus an additional $71,898 for police details. The Citywide Illegal Connection Investigation Program, Phase 2 (CWI2) was carried out between 2009 and 2012. Total cost for the CWI2 contract was $1,660,000, plus an additional $22,343 for police details. The contract for the Citywide Illegal Connection Investigation Program, Phase 3 (CWI3) was executed in May 2012. The contract ceiling for CWI3 is $2,079,647 and the contract duration is four years. These costs for the SBI and the three CWI contracts do not include the cost to correct the illicit discharges found, nor do they include other costs borne by the Commission for activities, such as performing additional dye tests, cleaning pipes and manholes, program management, construction oversight and other support services. 2.4 STATUS OF 2012 SUB-CATCHMENT INVESTIGATIONS The CWI2 Program concluded in November 2012. The final report included percentages of sub-catchment area investigations completed as of the close of the project. Table 2-3 provides the percent complete for each sub-catchment area that was investigated under CWI2, or in the previous CWI1. The calculations were based on investigations completed between November 2004, and the conclusion of field investigations under CWI2, on June 30, 2012. The percent complete by manholes was calculated based on the total number of stormwater and common manholes in the sub-catchment area that were systematically investigated 2, divided by the total number of stormwater and common manholes in the sub-catchment area. The percent complete by linear footage of pipe was calculated based on the total footage of storm drain pipe in the sub-catchment area that was systemically investigated, divided by the total footage of storm drain pipe in the sub-catchment. In accordance with the Consent Decree, in its Compliance Reports, the Commission will report the overall percent complete for every sub-catchment area in its MS4 system, as well as the percent complete for each sub-catchment during the reporting period. Similar information will be provided in future Stormwater Management Reports. 2 As described in the Commission s IDDE Plan, not every storm drain manhole in a sub-catchment area is inspected. Some manholes are inferred to be void of contamination, based on the results of inspections of manholes upstream and downstream, or on dye tests of adjacent buildings. 2-4

2.5 CORRECTION/REPAIR OF ILLICIT DISCHARGES Correction and repair of illicit discharges is discussed in the Commission s IDDE Plan, which is provided in Appendix D. Of particular note, in 2012, the Commission amended its Sewer Lateral Assistance Program to provide financial assistance to property owners to line or relay leaking sewer laterals, including those sections on private property. Under the program, owners of verified leaking sewer laterals may be reimbursed up to $4,000 for lining or relaying their leaking sewer lateral by a licensed bonded contractor. A leaking lateral must be lined or relayed from inside the building foundation to the public sewer in the public way. To obtain reimbursement property owners must obtain three or more quotes from contractors to repair the leaking lateral and the lateral must be verified as leaking by the Commission. The Commission reviews the submission, the owner signs a waiver and Commission authorizes the owner to proceed with the work. After the owner reports repair of the sewer lateral, the Commission or its contractor will perform a dye test to confirm that the lateral is not still leaking into the drain system. 2.6 SUPPLEMENTAL ENVIRONMENTAL PROJECT In accordance with the terms of the Consent Decree, the Commission must implement and complete a Sewer Lateral Lining Program Supplemental Environmental Project (SEP). In September, 2012, the Commission identified a preliminary list of twenty-six (26) buildings with verified leaking sewer laterals. As required by the SEP, the Commission will line each of the private sewer laterals together with the connection to the Commission s sewer main in an integrated system from the building foundation to the Commission s public sanitary sewer. A Request for Proposals for a contractor to assist the Commission in implementing the SEP was advertised on September 10, 2012. Proposals were due on October 19, 2012. The Commission s Board of Commissioners approved award of the SEP contract to Rooter Express, LLC on December 17, 2012. 2.7 2012 ILLICIT DISCHARGE REMEDIATION SUMMARY The Commission identifies two types of illicit discharges: direct illicit connections and sanitary sewer defects i.e. leaking sewer laterals. Direct illicit connections include sanitary sewer laterals that are directly connected to storm drains in the public way; these are usually corrected by a Commission contractor. Direct connections also include sanitary connections, such as from a single toilet or washing machine, to an internal building drain; these require the owner of the property to correct. The leaking lateral illicit discharges are those laterals that the Commission has confirmed are properly connected to the sewer system; however, testing of the sewer laterals verified that they leak sewage into the drain system. The methods used by the Commission to eliminate illicit discharges are described in the IDDE Plan provided in Appendix D. There were twenty-eight (28) direct illicit connections at the start of 2012. In 2012, fiftytwo (52) new direct illicit connections were verified. As of the end of 2012, seventy- 2-5

eight (78) direct connections had been corrected by the Commission s contractor or by the property owners. Only two (2) direct illicit connections remained uncorrected as of the end of 2012. At the start of 2012, there were fifteen (15) verified leaking laterals. Prior to 2012, in an attempt to stop the leakage, all of these laterals were lined at their connection to the sewer system under Commission contract 10-309-010. After they were lined at their connections, it was verified that they still leaked sewage into the drains system. In 2012, sixty-two (62) leaking sewer laterals were newly verified and twenty-nine (29) leaking sewer laterals were repaired. Of those repaired in 2012, eleven (11) were lined at their connection to the sewer main and no longer leaked into the drain system. Despite being previously lined at the connections under contract 10-309-010, fourteen (14) laterals still leaked sewage to the drain system. In 2012 the 14 laterals were lined under Commission contract 11-206-011, which involved lining the laterals from the cleanout in the building, up to and including the previously installed lining at the connection to the sewer system. Four (4) laterals, which had been previously lined at their connections to the sewer system under contract 10-309-010 still leaked. These were referred to the owners who had them repaired in 2012. As of the end of 2012, forty-eight (48) leaking sewer laterals remained unrepaired. Of those, forty-five (45) were issued enforcement notices on September 21, 2012. The September 21, 2012 notice allowed the owners 60 days to repair their laterals. On November 9, 2012, a second notice was sent to owners that had not repaired their leaking laterals. The November 9, 2012 notice served to inform owners about the Commission s newly expanded Sewer Lateral Repair Program, and to remind owners of the requirement to repair their laterals. On January 24, 2013, 41 owners still had not repaired their laterals and were sent a third Enforcement Notice. The third Enforcement Notice established the deadline (schedule) of April 30, 2013, for repair of the leaking laterals by the owners. Four (4) owners were not issued the third Enforcement Notice because they were located within the beach areas covered by the Supplemental Environmental Project Program (described in Section 2.6). The owners of two (2) of the outstanding leaking laterals had not been issued Enforcement Notices as of the end of 2012. They are also located within the beach areas covered by the SEP. These leaking laterals will be scheduled for correction under the Supplemental Environmental Project. In total, in 2012, one-hundred and fourteen (114) new illicit discharges were identified, and one-hundred and seven (107) illicit discharges were corrected or repaired. Fifty (50) illicit discharges remained uncorrected or unrepaired at the end of 2012. Calculations of cost to remove illicit discharges The cost to the Commission to correct seventy-eight (78) direct illicit discharges was $506,328. Of this amount, $7,500 was monies reimbursed to an owner to install an ejector pump. The total cost to the Commission to repair twenty-nine (29) leaking laterals was $227,194. Of this cost $220,794 was expended for Commission contracts 2-6

10-309-010 and 11-206-011, and $4,600 was reimbursed to owners to repair leaking laterals on their property under the Sewer Lateral Assistance Program. This cost does not include the cost of permits, inspection fees, pavement restoration or police details; it does not include costs covered by property owners who were responsible for making internal corrections on their own property. In total, $733,522 was expended by the Commission to correct or repair illicit discharges in 2012. Calculations of sewage removed The Commission estimates the wastewater removed by elimination of an illicit discharge based upon water use records for the property where the illicit discharge was located. Average daily water consumption is calculated based on the previous 24 month period. For direct illicit connections it is assumed 10 percent of the water is consumed and only 90 percent was discharging to the drain system. If only a portion of the building contributed to the direct illicit discharge the figure is adjusted accordingly. It is not possible to know exactly how much sewage is leaking into a drain from a leaking sewer lateral. So the Commission makes a best estimate. For a leaking sewer lateral it is assumed that, because a proper sewer lateral exists at the location, only one-third of the sanitary flow is entering the drain system. Due to the Commission s efforts in 2012, an estimated 24,357 gallons per day (gpd) of wastewater was removed from the storm drainage system and receiving waters by correcting direct illicit connections. In 2012, an estimated 2,329 gpd of wastewater was removed by the storm drainage system and receiving waters by repairing leaking laterals. In total, in 2012, an estimated 26,686 gpd of wastewater was removed from the storm drainage system and receiving water by correcting or repairing illicit discharges. 2012 Illicit Discharge Remediation Program Summary Direct Illicit Connections Listed January 1, 2012...28 Direct Illicit Connections Identified in 2012...52 Direct Illicit Connections Corrected in 2012...78 Direct Illicit Connections Outstanding December 31, 2012....2 Leaking Laterals Listed January 1, 2012...15 Leaking Laterals Verified in 2012...62 Leaking Laterals Repaired in 2012...29 Leaking Laterals Outstanding as of December 31, 2012...48 2-7

At the end of 2012, forty-eight (48) verified leaking laterals remained to be repaired. Of those, seven (7) laterals will be repaired under the SEP Program. The other forty-one (41) are the responsibility of the owner to repair. The owners of the 41 non-sep laterals have been given a schedule for the repair of the laterals. Under the schedule the laterals must be repaired by April 30, 2013. 2-8

3.0 STORMWATER MANAGEMENT ACTIVITIES The Stormwater Management Program consists of a variety of programs, activities, and best management practices aimed at preventing the discharge of pollutants to storm drains and receiving waters. These measures include maintenance, structural, managerial, regulatory, and educational programs. Key elements of the Commission s Stormwater Management Program and Stormwater Management Plan implementation are described in this section. 3.1 OPERATION AND MAINTENANCE OF STRUCTURAL CONTROLS Combined sewer overflows, sanitary sewer overflows, sewage infiltration into storm drains and system backups can be prevented by maintaining the capacity and structural integrity of the sewerage and drainage systems. The Commission accomplishes this by cleaning, repairing or replacing sanitary and combined sewers and storm drains, separating combined sewers, preventing and correcting sewer system overflows, and by preventing and removing infiltration and inflow to the sewer system. To determine where structural deficiencies exist and where repairs are needed the Commission performs television inspections of sewers and drains. a. Storm Drain and Sewer Maintenance by BWSC Staff The Commission s Operations Division is responsible for smaller sewer and drain related repair, maintenance and cleaning jobs, as well as some television inspections of sewers and drains. In 2012, the Commission jetted, vactored or rodded 484,426 linear feet of pipe. Approximately 1,565 cubic yards of material was removed during these operations. In 2012, the Commission owned five (5) vactor high-pressure cleaning trucks to clean accumulated materials from sewers and drains, six (6) jet trucks, one (1) multi-rodder truck, and two (2) hydraulic bucket machines to clear blockages. To determine where structural deficiencies exist and where repairs are needed, the Commission crews performed television inspections of 42,589 linear feet of sewer and drain pipe in 2012. In conjunction with the storm drain and catch basin cleaning programs, the Commission routinely clears debris from twelve (12) brook inlets and outlets throughout the City. Since the primary purpose of this practice is to prevent upstream flooding, the cleaning is typically performed immediately prior to major storm events and usually they are checked after storm events to determine if follow up cleaning is needed. The locations and frequency of cleaning is provided in Table 3 1. 3-1

b. Catch Basin Maintenance The Commission has approximately 30,803 catch basins in its sewer and drainage systems. Other catch basins in the city are owned by other public agencies such as the state Department of Conservation and Recreation, Mass Department of Transportation, or are located on private property. The Commission currently owns six (6) clamshell trucks. Commission forces have been augmented by contract resources and equipment since 2001. Contract resources are instructed to clean any catch basin containing eighteen (18) inches or more of sediment and any basin for which a recent cleaning record does not exist (i.e. does not have any record of cleaning within the past 2 ½ years for catch basins with a 4-foot or greater sump; or within 15 months for catch basins with a sump less than 4 feet). In 2012, Commission and contract resources performed 14,320 catch basin cleanings, removing an estimated 16,286 cubic yards of material. Catch basin cleanings are transported to the Material Handling Facility on Alford Street where they are temporarily stored to de-water until transferred for proper off-site disposal/reuse at and approved disposal facility. c. Commission Particle Separators The Commission evaluates whether installation of particle separators is feasible and appropriate when designing storm drain capital improvement projects. One new particle separator was added to the Commission s system in 2012. The particle separator was constructed by MassDOT during the Central Artery/Tunnel Project, and ownership was handed over to the Commission in 2012. The Commission currently owns sixteen (16) particle separators. Information regarding the various particle separators, including their locations, receiving waters, and inspection and cleaning dates in 2012 is summarized in Table 3-2. All sixteen (16) particle separators were inspected in 2012. Of those, only three (3) needed cleaning, and one couldn t be cleaned due to defects in the structure. The structure will be inspected under the Commission s Wastewater and Storm Drainage Facilities Plan Project and repaired as necessary. d. Large Storm Drain and Sewer Programs under BWSC s CIP Large cleaning and maintenance jobs are performed by outside contractors under the Commission s Capital Improvement Program. The Commission s three-year Capital Improvement Program (CIP) is updated annually. The 2012-2014 CIP included $103.6 million for sewer and drain related projects, of which $40.3 million was earmarked for 2012. A copy of the 2012-2014 Capital Improvement Program is available upon request from the Commission. 3-2

3.2 FLOOD CONTROL PROJECTS Receiving water and stormwater quality impacts are considered whenever the Commission undertakes capital improvements to the drainage system, including those relating to flood control. For each project, consideration is given to re-designing or retrofitting the drainage system to provide additional pollutant removal capability. a. Muddy River Flood Control Program This project involves a multidisciplinary approach to improving the Muddy River watershed and the adjacent parklands, referred to as the Emerald Necklace located in Boston, Brookline and Newton. The project, which is managed by the Boston Parks and Recreation Department and the Town of Brookline, involves measures to increase the hydraulic capacity of the river and implementation of stormwater Best Management Practices in the watershed to improve stormwater and receiving water quality. Between 2000 and 2002, the Commission provided $1.5 million in funding to support the project. Dredging of the Charlesgate portion of the Muddy River was completed in 2002. Also in 2002, the Commission reviewed the Draft Environmental Impact Report and submitted comments to MEPA in April. The Commission reviewed the Final Environmental Impact Report in April 2003 and no comments were submitted. The Commission continues to advise on best management practices and stormwater management for this program by participating in meetings held with the Boston Parks and Recreation Department, Town of Brookline representatives, consultants responsible for implementing the program and the Muddy River Citizens Advisory Committee. Construction on this project, including day-lighting the Muddy River near Park Street, managed by the Boston Parks Department and Brookline commenced in 2012 and will continue in 2013. 3.3 SEWER SYSTEM OVERFLOW CONTROL AND RESPONSE In compliance with the Consent Decree the Commission has expanded its oversight over sewer system overflows ( SSOs ). On September 23, 2012, the Commission instituted a program (including IPad application and Oracle SSO database) to track and report all public and private SSOs to EPA and DEP within 24 hours pursuant to Part E of the Consent Decree. Prior to commencement, the Commission performed internal training of Commission personnel in Engineering Services and Operations Division related to SSO response. On November 21, 2012, the Commission submitted an SSO Emergency Response Plan (SSOERP). The objective of the SSOERP is to provide a standardized set of actions for the Commission to follow in the event of an unpermitted discharge (overflow) from the sanitary and combined sewer system. In addition, the implementation of the SSOERP accomplishes the following objectives: 3-3

Minimize an SSO s impact on public health, public safety, and property damage. Comply with regulatory and enforcement reporting and public notification requirements. Minimize the reoccurrence of SSOs. Minimize the Commission s liability. The following elements are included in the SSOERP: Description of the types of sewers and discharges addressed by the SSOERP. An outline of the Commission s collection system inventory and staff, equipment and hardware/software for responding to SSOs. Procedures for receiving notifications of a possible SSO, and protocols for internal notifications about confirmed SSOs with the Commission s collection system and initial notifications to DEP, EPA and other authorities such as the MWRA. Procedures for responding to SSOs. Procedures for documenting and reporting SSOs. Descriptions of the means of notifying the public affected by an SSO. Description of the activities to be taken after an SSO has been remedied. Objectives and methods for training and preparing staff in regards to the SSOERP. Once it has been confirmed that an SSO is the responsibility of the Commission, within 24 hours the Commission notifies EPA and DEP. EPA and DEP are notified for any privately caused SSO exceeding 100 gallons or determined potentially may impact public health. Other parties may be notified depending on the extent and potential impact of the overflow. Within five days of an SSO, BWSC completes a post-remediation investigation of the SSO and submits it to DEP. The report includes a characterization of the SSO and a discussion of the planned actions to prevent recurrence. 2012, the Commission responded to, investigated, and/or reported to EPA and DEP, a total of 189 SSO events. Details regarding each SSO addressed by the Commission are being provided in the Commission s semi-annual Consent Decree Compliance Reports. 3.4 ILLEGAL DUMPING AND EMERGENCY SPILL RESPONSE The Commission s Sewer Use Regulations prohibit the dumping of any material into a catch basin, including any solid waste, construction debris, paint or painting product, antifreeze, hazardous waste, oil, gasoline, grease and all other automotive and petroleum products, solvents and degreasers, drain cleaners, commercial and household cleaners, soap, detergent, ammonia, food and food waste, grass or yard waste, leaves, animal feces, dirt, sand, gravel or other pollutant. Illegal dumping to catch basins carries a fine of up to $5,000 per day of violation under the Commission s Sewer Use Regulations. 3-4

Reports of illegal dumping to catch basins are directed to the Field Engineering Division which dispatches staff immediately to investigate. Upon investigation, if the violator can be identified, the violator is required to pay for cleaning of the affected catch basins, sewers, or storm drains. If the Commission does not observe the dumping in progress, but has good reason to believe a particular party is responsible, the Commission may verbally warn them of the environmental and legal ramifications of the action. When the violator cannot be identified, the Commission pays for a licensed contractor to clean out the affected catch basins, sewers and drains. Commission crews are available 24-hours a day to assist the Department of Environmental Protection, the Boston Fire Department and the U.S. Coast Guard in determining where a hazardous spill has entered or could potentially enter the Commission s wastewater or storm drainage systems. If the spill has entered either system, Commission personnel determine how far the contamination has traveled and whether there is the risk of an overflow to a waterway. The Commission also attempts to trace the spill upstream to locate and identify its source. When the source of the spill cannot be determined, the Commission pays for a licensed contractor to clean up the spill. In 2012, Field Engineering responded to 84 reports of a potential spill, leak, or report of illicit dumping. Table 3 3 lists the incidences to which the Commission responded in 2012. Field Engineering issued violation/enforcement notices in eleven (11) instances. Fines were issued in one (1) instance. 3.5 DRAINAGE DISCHARGE PERMITS Article C, Section 5 of the Commission s Sewer Use Regulations describes the discharge prohibitions and restrictions applicable to the Commission s storm drainage system. Under the Sewer Use Regulations any discharge of wastewater or other waters not composed entirely of stormwater into a building storm drain or a Commission storm drain is prohibited, except as authorized by the regulations. Authorized discharges include discharges for which the owner has obtained both a Drainage Discharge Permit from the Commission and an NPDES Permit or NPDES Permit Exclusion from EPA, as well as such discharges as river or stream flow, rising groundwater, uncontaminated groundwater, waters from hydrant flushing, and other potable water sources associated with the maintenance of the water distribution system or firefighting, irrigation water, and street and pavement wash waters. Discharges requiring a Drainage Discharge Permit include permanent subsurface drainage, non-contact cooling water, non-contact industrial process water, or waters associated with hydrological testing, groundwater treatment/remediation, and removal and installation of an underground storage tank. Drainage Discharge Permits are issued by the Commission s Field Engineering Division. The Commission may deny or condition a Drainage Discharge Permit to prevent the discharge of contaminants to the storm drainage system. Failure to obtain a Drainage Discharge Permit from the Commission carries a fine of up to $1,000 per day of violation under Sewer Use 3-5

Regulations. In 2012, the Commission issued eight (8) Drainage Discharge Permits for discharges to storm drains. The requirements for Drainage Discharge Permits are described in the Commission s Requirements for Site Plans, and developers and potential dischargers are informed of the requirements when they request a General Service Application for a building sewer or building storm drain connection. In addition, owners and developers are informed of the Drainage Discharge Permit requirements through comment letters submitted by the Commission to Massachusetts Environmental Policy Act (MEPA) Unit and the Boston Redevelopment Authority in response to Environmental Impact Reports. 3.6 DEVELOPMENT AND REDEVELOPMENT a. Sewer Use Regulations and Site Plan Review The majority of the Commission s stormwater management controls are enforced through its Regulations Governing the Use of Sanitary and Combined Sewers and Storm Drains (the Sewer Use Regulations). The Sewer Use Regulations were adopted in 1983 and amended in 1989. They were amended again in 1998 to strengthen and clarify the requirements, particularly as they pertain to stormwater discharges. In 1998, the Commission also amended its Penalty Schedule by adding and increasing the fines for several Sewer Use Regulation violations. The Commission requires that a General Service Application and a site plan be submitted for every new or reconstructed water, sewer, or storm drain service connection. The Commission s Requirements for Site Plans assist developers, builders, architects, engineers, and others in preparing site plans that conform to the Commission s Sewer Use Regulations and to help them secure the necessary approvals from the Commission. The site plan must be approved by the Commission s Chief Engineer before construction may begin, and it will not be approved unless it complies with the Commission s Requirements for Site Plans and Sewer Use Regulations. The site plan review provides an opportunity to review the components of the project and condition the approval on compliance with the Commission s Sewer Use Regulations, Requirements for Site Plans, and other requirements. The Commission s Requirements for Site Plans are updated as needed, generally about once a year. In 2012, 440 site plans were approved by the Commission s Chief Engineer. Requirements contained in the Sewer Use Regulations and Requirements for Site Plans relating to developments in Boston include the following: Filing Notices of Intent and Stormwater Pollution Prevention Plans The Commission recently revised its Requirements for Site Plans to include provisions for stormwater management at Construction Sites (as defined in the Consent Decree). The Requirements for Site Plans now specifically require construction site operators, 3-6

where applicable, to file Notices of Intent with EPA for NPDES General Construction Permits, and they must submit to the Commission Stormwater Pollution Prevention Plans (SWPPP). Also, construction site operators, where applicable, are required to use and maintain appropriate structural and non-structural BMPs to minimize the discharge of pollutants from construction sites to the Commission s MS4. Drain Layers License: Persons installing new building sewers and storm drains, or repairing or maintaining existing pipes must possess a Drain Layers License issued by the Commission. To obtain a Drain Layers License, persons must pass a written test given by the Commission s Engineering Customer Services Division. Test questions are typically drawn from the requirements provided in the Commission s Sewer Use Regulations, including those pertaining to illegal sanitary connections to storm drains, non-stormwater discharges, requirements for new construction and catch basin dumping. Drain Layers Licenses are renewed annually. The Drain Layers Licensing requirement provides the opportunity to educate drain layers in Boston as to the Commission s rules and regulations, including those pertaining to stormwater. Twenty-two (22) new Drain Layers Licenses were issued in 2012, and 424 were renewed. Inspections of New Connections: Connection of a building sewer to a storm drain is prohibited under the Commission s Sewer Use Regulations and carries a fine of up to $5,000 per day of violation. To ensure proper connection, the Commission requires that all new, repaired or modified service connections be inspected by a Commission inspector before the services are covered over by the contractor. Failure to have the connection inspected before covering it over carries a fine of up to $750 per day under the Commission s Sewer Use Regulations. As an added measure, new sewer connections must be dye tested by the Commission once construction is completed. Failure to have a new sewer connection dye tested carries a fine of up to $500 per day. The Commission may require that a repaired or modified service connection be dye tested. In 2012, the Commission s Engineering Field Services Division performed 490 GSA related dye tests. On-site Retention of Stormwater: Under the Commission s Site Plan Requirements and Sewer Use Regulations, developers of new projects are required to evaluate the feasibility of retaining stormwater on-site. On-site retainage of stormwater is required whenever site conditions permit as determined by the Commission. On-site retention of stormwater serves to limit peak discharge rates, recharge groundwater, and remove 80 percent of total suspended solids in the flow to the extent feasible. This requirement is consistent with the Department of Environmental Protection s Stormwater Management Policy which establishes standards for stormwater management for development. In 2012, the Commission approved 270 projects that included installation of dry wells or other type of infiltration device. Table 3 4 provides the addresses of the devices approved in 2012. 3-7

Controls for New Parking Lots: In order to prevent oil, grease and sediments from discharging to open waterways, the Commission requires that developers install particle separators on all newly constructed storm drains that serve outdoor paved areas of 7,500 square feet in size or greater. The Commission may require particle separators on existing storm drains from existing outdoor parking areas, where appropriate. This requirement has been in place since 1992. Parking lot particle separators are typically located on private property; therefore, their maintenance is the responsibility of the property owner. Design criteria for particle separators are set forth in the Commission s Guidelines for Developers for the Installation, Operation and Maintenance of Grit and Oil Separators, a copy of which is included in the Commission s Requirements for Site Plans. In 2012, the Commission approved installation of particle separators at 19 locations. Table 3 5 provides the addresses of the devices approved in 2012. Drainage Discharge Permits: The Commission requires a Drainage Discharge Permit for all non-stormwater discharges to its drainage system, including construction site dewatering, permanent subsurface drainage, non-contact cooling water, non-contact industrial process water, and waters associated with hydrological testing, groundwater treatment/remediation, and removal and installation of an underground storage tank. The Commission may deny or condition a dewatering permit to prevent contaminated drainage from entering the sewer or drainage system. Failure to obtain a Drainage Discharge Permit carries a fine of up to $1,000 a day under the Commission s Sewer Use Regulations. In 2012, the Commission issued eight (8) Drainage Discharge Permits for discharges to storm drains. Infiltration/Inflow Control: Newly constructed and substantially renovated buildings must be constructed so as to minimize inflow and infiltration to the Commission s wastewater system. Stormwater, including roof runoff, must be kept separate from sanitary sewage at all times, and the connection of a building storm drain to a sanitary sewer is prohibited. For development projects requiring review under Massachusetts Environmental Policy Act (MEPA) and that add a significant amount of new wastewater flow to the sewer system, DEP currently requires a reduction of 4 units of infiltration or inflow for each new unit of wastewater added. The Commission supports the DEP in this requirement. Developers of large projects can propose their own I/I reduction measures and submit them for review and approval by the Commission; they can select I/I reduction projects from a database being developed by the Commission; or they can pay a fee to the Commission in lieu of implementing an I/I reduction project. Erosion and Sedimentation Control: Under the Sewer Use Regulations, anyone seeking to construct, repair or modify a sewer or storm drain service connection to the Commission s system, or to discharge under a Drainage Discharge Permit, may be required to prepare and implement an Erosion and Sedimentation Control Plan to prevent 3-8

the introduction of sediments into the Commission s sewers and storm drains. Erosion and sediment control is also reviewed by the City of Boston s Conservation Commission when the project falls within its jurisdiction. Fuel Dispensing Areas: Under the Commission s Requirements for Site Plans, stormwater runoff from fuel dispensing areas not covered by a canopy or other type of roof or enclosure must discharge through a particle separator or an approved oil trap before discharging to the Commission s storm drainage system or receiving waters. Catch Basin Castings: Commission contractors are required to install metal castings with a Don t Dump message on sidewalks near new or reconstructed catch basins. Boston City contractors also install the castings when new sidewalks are installed. The castings are provided to city hired contractors by the Commission at no cost. The Commission requires that private developers install permanent Don t Dump catch basin castings next to any new catch basin installed as part of their projects. The developers, as well as other parties interested in obtaining the castings may purchase them from the Commission s vendor. In 2012, the Commission issued 196 catch basin castings to contractors and other parties. Of those issued, 113 were for Boston Harbor, 48 for the Charles River and 35 were for the Neponset River. b. Development/Redevelopment and Coordination with Municipal Agencies The Commission s NPDES Stormwater Permit requires the Commission to assist, coordinate, and cooperate with city departments and agencies to ensure that development projects within Boston are conditioned on due consideration of stormwater quality impacts, that they conform to applicable state and local stormwater requirements, and that negative impacts to stormwater quality during the time construction is underway are prevented. The Commission reviews environmental impact reports and notices of project changes for projects in Boston submitted to the Massachusetts Environmental Policy Act (MEPA) Unit and the Boston Redevelopment Authority (BRA). Comments were submitted to the MEPA Unit, BRA and/or other parties for thirty-five (35) projects in 2012. In most cases, copies of the letters were also sent to the Boston Environment Department. Letters for nine (9) projects contained comments regarding the Commission requirements for particle separators. Letters for thirty-eight (38) projects contained comments about the Commission s requirement for retaining stormwater on site. Letters for forty (40) projects contained comments regarding the requirement for Stormwater Management Plans. Thirty-five (35) letters contained comments regarding the requirement for 4 to 1 I/I reduction. If appropriate, the letters informed the proponent that a Drainage Discharge Permit may be required for any temporary or permanent non-stormwater discharge to the drainage system. To further this goal, in 2012, the Commission executed intergovernmental agreements with the City of Boston Inspectional Services Department, Boston Public Works 3-9

Department, Boston Parks and Recreation Department, Town of Milton and Brookline Department of Public Works. 3.7 CONTROLS FOR CONSTRUCTION SITES In compliance with its NPDES Permit and the Consent Decree, the Commission has expanded its oversight over stormwater discharges from construction sites. On December 18, 2012, the Commission submitted to EPA and CLF a Construction Site Inspection and Enforcement Program plan. The program plan sets forth procedures for conducting inspection of construction sites, procedures for inspecting and monitoring stormwater Best Management Practices used at construction sites, describes the means by which contractors and developers will comply with the Commissions regulations, EPA and DEP regulations and the Clean Water Act, and how the Commission will enforces its regulations to ensure compliance with its NPDES Permit and the Consent Decree. The Commission has revised its Requirements for Site Plans to include provisions for stormwater management at Construction Sites. The Requirements for Site Plans now specifically require construction site operators to file Notices of Intent with EPA for NPDES General Construction Permits, and they must submit to the Commission Stormwater Pollution Prevention Plans (SWPPP). Also, construction site operators, where applicable, are required to use and maintain appropriate structural and nonstructural BMPs to minimize the discharge of pollutants from construction sites to the Commission s MS4. In 2012, the Commission modified its Requirements for Site Plans to include a summary review of construction site SWPPP submitted with site plans, to assess whether the plan reasonable include measures that address potential water quality impacts from construction. On June 12, 2012, the Commission executed a Memorandum of Agreement (MOU) with the City s Inspectional Services Department (ISD). Under the MOU the Commission and ISD agreed to continue coordinating building permit issuance and site plan approval, whereby the Commission will not approve any construction site over one (1) acre unless the discharge permit has been approved. Also, ISD and the Commission agreed to notify new applicants for building permits and site plans of their requirements to obtain NPDES Stormwater Permits for construction sites from EPA. On November 27, 2012, in cooperation with the City s Inspectional Services Department (ISD), the Commission hosted a training session for Commission and ISD personnel responsible for implementing the program. The Commission began inspecting construction sites in August of 2012. As of the end of 2012, thirty-two (32) site inspections had been performed of thirty-eight (38) construction projects by Commission staff. 3-10

3.8 INDUSTRIAL FACILITY STORMWATER POLLUTION PREVENTION In compliance with its NPDES Permit and the Consent Decree, the Commission is developing an Industrial Facility Stormwater Pollution Prevention (IFSPP) Program. Under the program the Commission must identify, inspect, and monitor pollutants in stormwater discharges to its drainage system from municipal landfills, hazardous waste treatment, storage, disposal and recovery facilities, facilities that are subject to EPCRA Title III, Section 313, facilities that hold, or are required to hold NPDES stormwater permits, and other industrial or commercial discharge that the Commission determines is contributing a substantial pollutant load to its drainage system. In September of 2012, the Commission solicited Requests for Proposals from consulting firms wishing to assist the Commission in the development of the program. Proposals were due on October 1, 2012. On November 2, 2012, the Commission s Board of Commissioners approved award of the contract to Stantec Consulting. The three-year contract with Stantec for the IFSPP Program was executed on November 16, 2012. The Commission must submit to EPA, DEP and CLF, IFSPP Program plan, an inventory of known industrial facilities, and develop a database to track relevant information, including enforcement and corrective action, relating to the industrial facilities. The IFSPP Plan, inventory and database will be submitted as required by the due date of February 19, 2013. 3.9 ROADWAYS As contained in its enabling act, the Commission s authority is limited to the operation and maintenance of the water distribution system and the wastewater collection and stormwater drainage systems which serve the City of Boston. The Commission s jurisdiction does not extend to the operation and maintenance of roadways. Through informal communications with officials from agencies having the responsibility for the management of city roadways, the Boston Public Works Department (PWD), the state Department of Conservation and Recreation (DCR), and the Massachusetts Department of Transportation, (MassDOT), the Commission learned that agency officials are well aware of the environmental issues relating to roadway management, specifically the use of roadway deicing chemicals and the benefits of frequent street sweeping. a. City of Boston Snow Removal and Road Deicing Practices Snow plowing and road deicing of most of the public roads in Boston are the responsibility of the PWD. PWD officials have emphasized that public safety is their primary concern in determining how much sand and salt is applied to roadways and that weather conditions dictate application levels; if the roads are icy and snow covered, sand and salt must be applied to produce a clear and dry roadway surface. The public safety issue is balanced by the fact that the more deicing chemicals are used, the greater the cost 3-11

to the City. Therefore, to keep costs at a minimum, the PWD uses only the amount of chemical needed to achieve the job. The PWD performs some of the snow removal operations on city streets and also has snow removal contracts. Snow is plowed to the side of the streets, but is not typically removed. A sodium chloride salt/sand mixture is used as a deicing agent, and application rates vary based on temperature and precipitation. Contractors use the City s supply of salt and sand during deicing operations. In fiscal year 2012 the PWD used 26,051 tons of salt. b. City of Boston Street Cleaning Sweeping of city owned streets is conducted by the PWD or by its contractors. According to the PWD, the City has two programs for street sweeping: Posted Street Cleaning and Non-posted Street Cleaning. All non-posted streets are cleaned once a week or more if necessary. The Posted Sweeping Program is separated between a Night Program and a Daily Program. Sweepers also clean up before and after special events, such as parades, road races and neighborhood festivals. The Night Sweeping Program includes an area from Massachusetts Avenue to the Waterfront that is swept on a nightly basis year round. The Night Sweeping Program also covers the City s major arterial routes throughout the City, which are swept once a week at night year round. The Daily Street Sweeping Program typically operates from April 1 st through November 30 th. PWD recently expanded the Daily Street Sweeping Program in the Beacon Hill, North End and South End, from March 1 st through December 31 st. Weather and budget conditions permitting, the program may begin earlier in the season and extend later into the fall. Each side of a posted city street on the Daily Street Cleaning Program is cleaned once every other week. Additional street sweepers may be contracted and city sweepers run more frequently during the fall leaf season. Parking bans (signs) posted on streets serve to educate the public and to have vehicles removed on certain days so sweeping can be thorough. The parking bans are enforced by the Boston Transportation Department. If cars are not removed on designated days, owners can be fined. The fine for not removing cars on the designated days is currently $40, plus an additional $90 for tow, storage and fees. Contractors are responsible for providing their own sweeping equipment and for disposal of the collected material. Since 2009, PWD requires its contractors to use vacuum type sweepers that have dust control systems and do not require water to operate. Because these types of sweepers don t require water, they can be operated year round, even in freezing conditions. The vacuum sweepers are believed to be more efficient at collecting smaller grit particles and dust. The new sweepers have saved the city thousands of gallons in water usage, and are in compliance with DEP regulations. 3-12

The PWD also has several small broom sweepers used to sweep small alleys and sidewalks. These sweepers are typically assigned to the more densely developed parts of the City, such as Chinatown, Downtown Crossing, and the North End. The composition of the material swept up varies seasonally with sand and sediments from winter deicing activities being most evident in the spring, leaf litter during the fall months, and light litter predominating during the summer. c. DCR Street Sweeping, Snow Removal and Road Deicing Practices Roads maintained by the DCR, such as the VFW Parkway, Storrow Drive, the Riverway, and the Fenway are served primarily by separate storm drains, which are owned and maintained by the DCR. DCR drainage systems in Boston are subject to the EPA s Stormwater Phase 2 program. DCR s stormwater management program includes good housekeeping measures, such as street sweeping of parkways, cleaning street drains and associated drainage systems and using control measures to protect sensitive receiving waters. Snow removal and deicing of DCR owned roads are managed jointly by the DCR and Mass DOT. 3.10 PESTICIDE, HERBICIDE AND FERTILIZER APPLICATION In 2001, the Commission completed an evaluation of existing measures to reduce the discharge of pollutants related to the application of pesticides, herbicides and fertilizers (PHFs) applied by municipal or public agencies. The Commission also evaluated the necessity to implement controls to reduce the discharge of pollutants related to the application and distribution of PHFs by commercial and wholesale distributors and applicators. The Commission performed evaluations of existing programs and data in 2001, and reported the results in the 2001 Stormwater Management Report. From the results of the evaluation, it was concluded that additional monitoring and controls for PHF use by municipal agencies and their contractors and for commercial and wholesale distributors was not warranted. Discussion of this analysis can be found in Section 3.6 of the 2009 Stormwater Management Report. 3.11 OTHER NON-STRUCTURAL STORMWATER MANAGEMENT MEASURES d. Used Motor Oil and Paint Collection Centers The Boston Public Works Department (PWD) operates Surplus Paint Products and Used Motor Oil Drop-Off and Recycling Centers in the neighborhoods of East Boston, Brighton, Roxbury, and Hyde Park. In 2012 each center was open one Saturday a month, 9 a.m. to 1 p.m., from May through August. Approximately 1,440 gallons of paint, thinner, stain and varnish, and motor oil, were collected and recycled in 2012. 3-13

e. Household Hazardous Waste Collection The Boston Public Works Department hosted four household hazardous waste collection events in 2012, as follows: June 9, and September 29, at the University of Massachusetts Campus, and June 30, and November 17, at the West Roxbury Public Works Yard. The events were promoted through the City s web site, local newspapers, and on signs posted in neighborhood business centers. The Commission s May/June and September/October issues of its Currents newsletter promoted the collection events. Copies of the newsletters are provided in Appendix A. The contractor for the hazardous waste collection charged for the service on a per car load basis. It was estimated each car carried 20 gallons of waste. In total, the hazardous waste collection days serviced 1,955 cars, for a total estimate of 29,100 gallons of waste collected. g. Yard Waste/Composting The Boston Public Works Department provides curbside collection of leaves and grass clippings in the residential sections of the city in the Spring and the Fall each year. To remind residents of the collection dates in 2012, the PWD distributed public service announcements to local radio and television stations. Door hangers were distributed in residential neighborhoods and signs were posted in neighborhood commercial centers. The Commission s September/October issue of its Currents newsletter promoted the fall 2012 collection effort. A copy of the newsletter is provided in Appendix A. h. Pet Waste Stormwater Monitoring Programs conducted by the Commission have indicated that pet waste is a significant source of bacterial contamination to stormwater. The City s dog fouling regulation, Section 16-1.10A of the Boston City Ordinances, also called the pooper scooper law, requires dog owners to remove and properly dispose of the waste left by their dog. Penalties under the ordinance are $50.00 for failure to produce a means of removal and $50.00 for failure to pick up the waste. The Animal Control Unit in the Boston Property Management Department is responsible for enforcing the dog fouling ordinance. It is also responsible for following up on reports of vicious dogs, ensuring dogs are properly licensed and leashed, and other animal control issues. Animal Control officials report that enforcing the pooper scooper law is difficult since the owner and dog must be observed in the act. Fines have been issued to dog owners in the past for violation of the pooper scooper law, although the exact number was not readily available. Two Animal Control officers are assigned to patrol city parks on a daily, rotating basis to ensure that park visitors with animals are complying with Boston s Animal Control related ordinances. In addition, the Commission s 2012 May/June issue of Currents included a feature designed to educate and encourage people to prevent contamination of stormwater by cleaning up after their pets. A copy of the Currents newsletter is provided in Appendix A. 3-14

f. Site Cleanliness Ordinance To address litter and rodent control problems, the City of Boston instituted a Site Cleanliness Ordinance in 2000. Under this ordinance, all businesses and large residential establishments using bulk dumpsters, including food and beverage establishments, automotive establishments, and bulk refuse container storage lots, must obtain a Site Cleanliness License from the Boston Inspectional Services Department (ISD). The application for a license must include a site plan showing the location of the dumpster, a plan and schedule for maintenance, a copy of the solid waste disposal contract, and a copy of a rodent/pest control contract. An additional license is required from the PWD if the dumpster is located on a public way. Inspectional Services officials perform annual inspections of establishments with any license issued by the Department, including a Site Cleanliness license. The Site Cleanliness license will not be renewed unless and until the establishment s dumpster complies with the city ordinance. Failure to comply with the Site Cleanliness Ordinance and obtain a Site Cleanliness license may result in fines of up to $1,000 a day. Repeated violations may result in closure of the business. ISD officials report that enforcement is very strict and that noncomplying businesses typically achieve compliance within days of being issued a violation notice. b. Abrasive Blasting or Chemical Cleaning Permits For any project involving repair or cleaning of existing masonry, the project proponent is required to obtain from the Boston Air Pollution Control Commission a permit for Abrasive Blasting or Chemical Cleaning. In accordance with the permits, applicants are required to provide a detailed description as to how chemical mist and run-off will be contained and either treated before discharge to the sewer or drainage system or collected and disposed of lawfully off site. Air Pollution Control Commission representatives perform periodic spot checks of project sites to ensure that the proponent is complying with the permit. The Air Pollution Control Commission reports to the Commission any violations they observe which result in the discharge of contaminants to drainage system from the cleaning operation. No violations were reported to the Commission by the Air Pollution Control Commission in 2012. 3-15

3.12 PUBLIC EDUCATION a. Billing Inserts On a bi-monthly basis in the water and sewer bills, the Commission provides customers with an informational newsletter called Currents. The newsletter is aimed at providing customers with useful information concerning the Commission s programs and activities. Issues of Currents announce upcoming events such as the Commission s community outreach meetings and city sponsored events such as household hazardous waste, oil and paint collections. In addition, articles feature tips on pollution prevention, and proper disposal of used motor oil, antifreeze, household hazardous materials, yard debris, pet waste and other wastes. In 2012, the May/June issue of Currents encouraged residents to pick up pet waste to prevent stormwater pollution and promoted the City s Household Hazardous Waste collection events in June. The September/October issue of Currents promoted the City s fall Leaf and Yard Waste pickup services and the Household Hazardous Waste collection events in September and November. Copies of the newsletters are provided in Appendix A. b. Commission Web Site The Commission s web site, located at www.bwsc.org, provides a variety of information concerning the Commission s programs, activities, and requirements. It provides the Commission s Sewer Use Regulations and Site Plan Requirements, it includes pollution prevention advice for residents, businesses and construction, and it provides information concerning the Commission s catch basin stenciling program. c. Catch Basin Stenciling and Castings Public awareness regarding the connection between catch basins and water quality is promoted through the Commission s Catch Basin Stenciling Program. Through the Catch Basin Stenciling, volunteers are mobilized to stencil Don t Dump messages next to catch basins. Upon request, the Commission coordinates stenciling projects and provides instruction, stencils, paint, rollers, brooms, informational leaflets, and safety equipment. The Catch Basin Stenciling Program is promoted through the Commission s web site and billing inserts and through press releases, community events and outreach meetings, presentations to public schools, and through local watershed associations. Organizations participating in the Commission s 2012 catch basin stenciling program were the Boston Harbor Association and the Advent School of Beacon Hill. Commission contractors are required to install metal castings with a Don t Dump message on sidewalks near new or reconstructed catch basins. Boston City contractors also install the castings when new sidewalks are installed. The castings are provided to 3-16

city hired contractors by the Commission at no cost. The Commission requires that private developers install permanent Don t Dump catch basin castings next to any new catch basin installed as part of their projects. The developers, as well as other parties interested in obtaining the castings may purchase them from the Commission s vendor. The Commission issued 196 catch basin castings to contractors and other parties in 2012. Of those issued, 113 were for Boston Harbor, 48 for the Charles River and 35 were for the Neponset River. d. Scoop the Poop Education The Commission s May/June 2012 issue of Currents was designed to encourage pet owners to clean up after their pets. A copy of the newsletter is provided in Appendix A. e. Stormwater Management Brochure for Small Commercial Businesses The Commission has prepared a brochure on stormwater management for small commercial businesses. The brochure is currently available on the Commission s website. The brochure is intended to increase awareness of the relationship between improper disposal of pollutants and contamination of receiving waters. It describes specific measures that can be taken by business owners and their employees to prevent the discharge of pollutants to the drainage system. The brochure is available and can be downloaded from the Commission s website. A copy of the brochure is provided in Appendix A. 3.13 SUPPORT FOR WATERSHED AND ENVIRONMENTAL AGENCIES AND ORGANIZATIONS Each year the Commission provides funding to Watershed Associations and Environmental Organizations to support their water quality monitoring programs and public education efforts. The Charles River Watershed Association, Neponset River Watershed Association, and the Boston Harbor Association each received $10,000 from the Commission in 2012. Support for the EPA, and DEP s watershed programs is provided on an ongoing basis by the Commission. As needed, the Commission shares monitoring and rain gauge data, investigates reports of illegal connections or other non-stormwater discharges to waterways, participates in planning meetings, and provides technical advice. 3-17

4.0 STRUCTURAL BEST MANAGEMENT PRACTICES AND GREEN INFRASTRUCTURE Under the Consent Decree the Commission must develop a plan for implementation of structural Best Management Practices (BMPs), Green Infrastructure and Low Impact Development (GI/LID) measures. The BMP Proposal, the Phase 1 BMP Implementation Plan, and the BMP Recommendation Report required by the Consent Decree will not be submitted until after the end of 2012. They will be reported on in future Stormwater Management Reports. 4.1 STORMWATER MODEL REPORT Pursuant to this requirement, on December 28, 2012, the Commission submitted a Stormwater Model Report to EPA, CLF and DEP. The report, developed by CDM Smith in conjunction with Commission staff, included a description of the model, a description of the results of model runs using a range of design storms and long-term continuousloading scenarios, a description of initial and ongoing model verification and calibration efforts, and estimated pollutant loadings by each sub-catchment area and sub-watershed. The report included ranked listing and evaluations of ranked listings for individual outfalls and sub-watersheds. The report contained an evaluation of each sub-catchment area, included the evaluation and quantification of impervious surface area, directly connected impervious area ( DCIA ), population density, land use classifications, pollutant loading, and availability of suitable property for the implementation of specific stormwater BMPs at targeted locations. The report contained a discussion of potential BMPs available for possible implementation, including all appropriate GI/LID techniques. It also contained a discussion of how the BMPs could assure consistency with all applicable wasteload allocations and the extent to which the BMPs would prevent Commission discharges from causing or contributing to a violation of water quality standards. 4.1 BOSTON COMPLETE STREETS INITIATIVE The City of Boston has developed the Complete Streets Initiative, under which incorporation of green infrastructure into street designs is required. Green infrastructure includes greenscapes, such as trees, shrubs, grasses and other landscape plantings, as well as rain gardens and vegetative swales, infiltration basins, and paving materials and permeable surfaces. The Commission supports the City in this endeavor. Information about the Complete Streets Initiative is available on the City s website at http://bostoncompletestreets.org/. 4-1

5.0 ASSESSMENT OF STRUCTURAL CONTROLS To comply with the Consent Decree the Commission will be required to evaluate the effectiveness of Best Management Practices. These evaluations will be reported in future Stormwater Mangement Reports as they are performed. 5.1 CATCH BASINS The Commission relies on catch basins as the primary means for preventing the transport of sediments, debris, and other contaminants to storm drains and receiving waters. The Commission has approximately 30,803 catch basins in its sewer and drainage systems. Other catch basins in the city are owned by other public agencies such as the state Department of Conservation and Recreation, Mass Department of Transportation, or are located on private property. The Commission currently owns six (6) clamshell trucks. Commission forces have been augmented by contract resources and equipment since 2001. Contract resources are instructed to clean any catch basin containing eighteen (18) inches or more of sediment and any basin for which a recent cleaning record does not exist (i.e. does not have any record of cleaning within the past 2 ½ years for catch basins with a 4-foot or greater sump; or within 15 months for catch basins with a sump less than 4 feet). In 2012, Commission and contract forces performed 14,320 catch basin cleanings, removing an estimated 16,286 cubic yards of material. Catch basin cleanings are transported to the Material Handling Facility on Alford Street where they are temporarily stored until transferred for proper off-site disposal/reuse at and approved facility. In 2001 and 2002, the Commission s Stormwater Monitoring Program included a demonstration project to evaluate the effectiveness of catch basins in capturing solids. The results of the demonstration project (described in previous annual reports) indicated that a clean and well-maintained catch basin will remove between 10 to 33 percent of the total solids from stormwater flow through the basin. The data also suggested that a catch basin s ability to remove solids diminishes as the sump of the catch basin approaches half full. These findings are consistent with the conclusions of other similar studies reported in the literature. The Commission continued to measure the depth of sediment in the catch basin sumps on a quarterly basis through the beginning of 2004. The results showed that sediment depths in the two catch basins monitored continued to increase between April 2002 and May 2003, but began to level off and even decline, as the basins approached 50 percent full. 5-1

This finding appears to confirm that the catch basin had achieved their maximum effectiveness. Under the Commission s Catch Basin Inspection and Cleaning Program the sediment depths in one hundred catch basins were monitored between January 2002 and April 2003, to determine the factors that effect how quickly catch basins become full. Variables considered in selecting the catch basins to be monitored included slope, land use and the size of the tributary area, the type of road (highly traveled road vs. back road), and tree cover. The selected catch basins were inspected four times each on a quarterly basis and the depth of sediment measured. No statistically significant correlation between land use and accumulation rates was observed. Similarly, no correlation was observed based on slope, drainage area, or neighborhood characteristics. Some correlation with tree cover was observed, with the catch basins located in areas of denser tree coverage demonstrating as much as 50 percent higher accumulation rates as compared to basins with little or no tree cover. The data also exhibited a seasonal correlation, with the winter months demonstrating the highest accumulation rates. Based on the findings of the Commission s catch basin effectiveness analyses, the Commission s catch basins should continue to effectively remove sediments from stormwater runoff, provided that sediment levels are not allowed to exceed one-half of the capacity of each catch basin s sump. 5.2 PARTICLE SEPARATORS The Commission currently owns 16 particle separators. All sixteen (16) particle separators were inspected in 2012. Of those, only three (3) needed cleaning, and one couldn t be cleaned due to defects in the structure. The structure will be inspected under the Commission s Wastewater and Storm Drainage Facilities Plan Project and repaired as necessary. Information regarding the various particle separators, including their locations, receiving waters, and amount of material removed at each cleaning between 2002 and 2012 is summarized in Table 5 1. The cleaning data provided over the last several years demonstrated that there are significant differences in the amount of material removed from each separator from year to year, although the reasons were unclear. There are many variables which could affect the amount of material retained in a separator, including, frequency and intensity of rain and snow storms, land use, topography and size of the area tributary to the particle separator, season during which the separator was cleaned and design factors. The Commission typically uses a vactor truck with a vacuum hose to clean its particle separators, and this equipment is not conducive to accurate quantification of material removed. The amount of material removed is estimated by the operator and not measured. Each operator may estimate the amount of material removed differently than others. For these reasons it is difficult to establish which factor(s) determine how well a 5-2

particle separator removes solids, or why one particle separator appears to capture more sediment than another. Also unclear, was whether the amount of material removed at each cleaning represented the cumulative sediment load captured by the device over the year, or that it was only the amount of material that happens to be in the separator at the time of cleaning. To examine this issue more closely, in 2010, the Commission inspected and cleaned two of its particle separators (Fenwood Road and Walter Street) approximately once a month between March and October 2010, to determine if there was any difference in the amount of material removed. The results of the Particle Separator Assessment 2010 are included in Table 5-1. 5-3

6.0 WATER QUALITY MONITORING On December 28, 2012, the Commission submitted a Stormwater Model Report to the EPA, DEP and CLF, as required under the Consent Decree. As part of the Stormwarer Model (Model) development the Commission and its contractor CDM performed extensive water quality sampling of the storm drain system. The contract for the Model included flow monitoring and water quality sampling at 20 sites, model development, and calibration of the model to those data. The contract also included analysis of the impacts of potential stormwater controls to help the Commission satisfy Consent Decree requirements. The Model was used to estimate flows and loads for 13 key parameters, including nutrients, bacteria and metals. It was used to analyze a set of alternative that aim to reduce loading of pollutants from the drain system to receiving waters. That analysis was performed as a starting point for more in-depth studies into the feasibility and expected benefits of implementing green infrastructure and low impact development (LID) in the City of Boston. The Model was used to simulate the impacts of the alternatives on the loading of phosphorus and bacteria from select watersheds draining to different receiving waters. Overall, the alternatives modeling indicated that expansion of current programs and policies (illicit discharge removal, site plan requirements, and Boston s Complete Streets initiative) will measurably help the Commission comply with its permit and meet the terms of TMDLs governing its receiving waters. Other stormwater quality monitoring and demonstration programs required under the Commission NPDES Permit were completed within the Permit s first five years. Descriptions of those programs were provided in previous Stormwater Management Reports. In 2010, the Commission completed another monitoring program. Under the Stormwater Quality Evaluation Program, the same sites monitored during the first five years of the permit were monitored. The purpose of the monitoring was to evaluate how water quality had changed over time, and to try to determine pollutant sources. The Stormwater Quality Evaluation Program was completed near the end of 2010 and the final report was completed in May 2011 and previously reported. The full report is available upon request. 6-1

7.0 WATER QUALITY IMPROVEMENTS The Commission enhanced and expanded its Stormwater Management Program in 2012 to improve stormwater quality and ensure compliance with the Consent Decree lodged in August 2012. The Commission expects these changes will positively impact stormwater quality in the City. However, quantifying the improvement is difficult to measure, since many of the measures used by the Commission are non-structural, and are aimed at controlling the introduction of pollutants to the storm drain system at their sources, as opposed to end-of-pipe treatment. Therefore, the Commission assesses water quality improvements based on measures that are quantifiable, such as how much wastewater is removed from the drainage system when an illegal connection is eliminated, and how much sediment is removed from stormwater runoff by structural devices. 7.1 ILLICIT DISCHARGE ELIMINATION The Commission believes that eliminating illicit discharges to storm drains is the most environmentally beneficial and cost-effective means of improving water quality. In 2012, the Commission corrected 107 illicit discharges, thereby eliminating the discharge of an estimated 26,686 gallons per day (gpd) of wastewater to the drainage system and receiving waters. Between 1986, when the Commission first began correcting illicit discharges, and the end of 2012, the Commission removed 1,272 illicit discharges, thereby eliminating the discharge of an estimated total of 620,962 gallons of wastewater per day to the storm drainage system and receiving waters. 7.2 SEWER, DRAIN, CATCH BASIN AND PARTICLE SEPARATOR CLEANING In 2012, the Commission and its contractors removed an estimated 17,851 cubic yards of material from the Commission s catch basins, particle separators, and drains that might have otherwise ended up in local rivers and waterways. 7.3 BMPS ON PRIVATE PROPERTY Under the Commission s Sewer Use Regulations and Requirements for Site Plans, there are several provisions requiring the installation of structural best management practices by private parties, as described below. 7-1

a. Privately Owned Retention/Infiltration Devices On-site retainage and infiltration of stormwater is required for new and redevelopment projects, whenever site conditions permit, as determined by the Commission. Project developers are required to include a feasibility assessment for on-site retention of stormwater with the site plan submitted to the Commission for the project. On-site retention of stormwater serves to limit peak discharge rates, recharge groundwater, and remove 80 percent of total suspended solids in the flow to the extent feasible. This requirement is consistent with the Department of Environmental Protection s Stormwater Management Policy which establishes standards for stormwater management for development. On-site retention devices are usually owned by the owner of the property where they are located, and the owner is responsible for cleaning and maintenance. Owners of on-site devices are not required to provide data regarding solids removal rates to the Commission. However, the devices are expected to remove solids consistent with their designs. In 2012, the Commission approved 208 site plans which included installation of a dry well or other type of infiltration device. The addresses of the devices approved in 2012 were listed previously in Table 3 4. Since 1993, when the Commission first started tracking infiltration devices installed pursuant to site plans, 1,954 private development projects have included infiltration devices. b. Privately Owned Particle Separators In order to prevent oil, grease and sediments from discharging to open waterways, the Commission requires that developers install particle separators on all newly constructed storm drains that serve outdoor paved areas of 7,500 square feet in size or greater. The Commission ensures that particle separators on parking lots are included in the project design during site plan review. The Commission may require particle separators on existing storm drains from existing outdoor parking areas, where appropriate. This requirement has been in place since 1992. Parking lot particle separators are usually owned by the owner of the property where they are located, and the owner is responsible for their cleaning and maintenance. Owners of on-site particle separators are not required to provide data regarding solids removal rates to the Commission. However, the devices are expected to remove solids consistent with their designs. In 2012, the Commission approved 35 site plans which included installation of particle separators. The addresses of the devices approved in 2011 were previously listed on Table 3 5. Since 2001, when the Commission first started tracking particle separators installed pursuant to site plans, 310 private development projects have included installation of particle separators. 7-2

8.0 ENFORCEMENT In 2012, the Commission strengthened its Enforcement against violators of its illicit discharge regulations to remove illicit discharges and connections from the Commission s MS4 system. Enforcement commences as follows: Once the Commission verifies that an illicit discharge must be corrected by the owner of a property, the Commission mails an initial letter of enforcement to the owner. The letter directs the owner to contact the Commission within a given time frames (typically 10 days) and submit a plan for correction within a designated time period (typically 30 days). If the owner fails to respond, and/or does not correct the illicit discharge within those time frames, a second notice is issued. The second notice imposes a deadline or schedule for compliance and notifies the owners that fines will commence after a given deadline for failure to comply. If the owner fails to respond or does not correct the illicit connection within the given timeline or schedule, the Commission issues a Fifteen Day Notice, pursuant to Chapter 6, Section 6.3 of the Commission Billing, Termination and Appeal regulations for Termination of Service. Under the Fifteen Day Notice, the owner is given 15 days to correct the illicit connection and notify the Commission. If the owner fails to respond to the Fifteen Day Notice and/or fails to correct the illicit discharge, the Commission mails to the owner, and posts on the premises of the illicit connection, a Final Notice and Demand. If the owner still fails to correct the internal connection after the posting of the Final Notice and Demand, the Commission issues fines to the owner and terminate water service. In 2012, the Commission issued 174 enforcement notices to the owners of 79 properties with verified direct illicit connections or illicit discharges from leaking sewer laterals. In 2012, Field Engineering responded to 84 reports of a potential spill, leak, or report of illicit dumping. Table 3 3 in Section 3 lists the incidences to which the Commission responded in 2012. Enforcement notices were issued by staff in eleven (11) of those instances. Fines were assessed in one (1) instance. 8-1

9.0 FINANCING STORMWATER MANAGEMENT The Commission s Enabling Act empowers the Commission to independently set rates and charges for the services that it provides. The Commission is required to establish fees, rates, rents, assessments, and other charges at a level and amount at least sufficient to pay the principal, premium, and interest on bonds issued by the Commission; to maintain its reserve funds as stipulated by its General Bond Resolution; to provide funds for paying the cost of all necessary repairs, replacements, and renewals of the water and sewer systems; and to pay any and all other amounts which the Commission, by law or by contract, is obligated to pay. The Commission has sufficient funds and equipment to carry out the stormwater management programs and activities required under the NPDES Stormwater Permit. A major portion of the Commission s Stormwater Management Program and NPDES Stormwater Permit compliance activities are achieved using existing in-house staff and resources. Staffing and equipment are budgeted under the Commission s Current Expense Budget (CEB), which is updated annually. Larger sewer and drain projects are funded under the Commission s Capital Improvement Program Plan (CIP). The Commission s three-year CIP is updated annually. 9.1 CURRENT EXPENSE BUDGET The 2012 Current Expense Budget provided for $301.8 million in revenues and expenses. This amount represented a 1.9 percent increase as compared to the 2011 budget. Of the total budgeted for 2012, $57.7 million was for direct expenses. The remaining $244.1 million was budgeted for the assessment by the Massachusetts Water Resources Authority ($185.5 million), Debt Service ($44.0 million), Capital Improvements ($13.9 million), Contractual Funding Obligations ($0.5 million), and the Safe Drinking Water Act Assessment ($0.2 million). In general, stormwater programs and activities are managed in-house by the Commission s Operations and Engineering Divisions. Approximately $23.4 million or 40 percent of the Commission s 2012 direct expense budget was for the Operations Division. Of the Operations Division s direct expense budget, about $13.6 million was for sewer and storm drain related operations. Approximately $7.7 million or 13 percent of the Commission s 2012 direct expense budget was for the Engineering Division. About $4.5 million of the Engineering Division s direct expense budget was for sewer and drain related work. Put another way, 9-1

about $18.1 million was budgeted for Operations and Engineering Division s direct expenses relating to sewer and drain work. Thus sewer and drain related work represents about 31 percent of the Commission s total direct expense budget. The Current Expense Budget for 2013 had not been finalized as of the writing of this report. Stormwater related programs and activities funded under the Current Expense Budget include: Illegal connection investigations and corrections Illegal connection prevention Illegal dumping and spill response Infiltration and inflow identification and reduction Issuing Drainage Discharge Permits Sewer and storm drain maintenance and general repair Catch basin and particle separator cleaning and maintenance Designing and installing new particle separators Site plan review New service inspections and dye tests Issuing drain layers licenses Planning, designing and constructing capital improvements System evaluations and Master Planning Reviewing Environmental Notification Forms and Environmental Impact Reports Public education Rain data collection 9.2 CAPITAL EXPENDITURES The 2012-2014 CIP included $103.6 million for sewer and drain related projects, of which $40.3 million was earmarked for 2012. The Commission s 2013-2015 CIP plan identifies $85.66 million for sewer and drain related projects, of which $44.8 million is earmarked for 2013. The complete 2013-2015 CIP plan is available on the Commission s website at www.bwsc.org. These costs do not include the cost of CSO separation projects that are funded by the MWRA under the MWRA s CSO Control Plan. However, they do include the Commission s costs for water and sewer work relating to the MWRA s CSO Control Plan that is not eligible for MWRA funding. Programmatic activities covered under the 2012-2014 CIP include the following: Construction of Best Management Practices and Green Infrastructure in Central Square East Boston Construct Best Management Practices and Green Infrastructure at City Hall Plaza 9-2

Construct Best Management Practices and Green Infrastructure in Audubon Circle at Beacon Street and Park Street Stormwater Fee Evaluation Industrial Facility Stormwater Pollution Prevention Program CSO Public Notification Program Preparation of a Wastewater/Drainage Facilities Plan Citywide Illegal Connection Investigation Program Elimination of illicit discharges to storm drains Lateral Lining Pilot Program Construction of a larger storm drain to alleviate constriction in the Dorchester Brook Sewer which currently causes backups during heavy rains. Cleaning and rehabilitation of overflow conduit 065 to the Fort Point Channel. Sewer separation and affiliated rehabilitation work in the St. Mary s Street area included in the CSO 036 area. Sewer separation of flows along a portion of A Street and West Second Street in South Boston to help reduce overflows to Fort Point Channel. Sewer separation of flows along Massachusetts Avenue in Lower Roxbury/North Dorchester. Sewer separation in the areas tributary to the Reserved Channel in South Boston. Sewer separation in the Dudley Square area A water quality evaluation of the Fort Point Channel Augmentation of the Commission s stormwater model. Disconnection of downspout in Jamaica Plain, Dorchester, Allston-Brighton, West Roxbury, Roslindale, South Boston and Hyde Park. Projects relating to sewer separation projects that are necessary, but are not eligible for funding by the MWRA. These include renewal and replacement of existing sewers and drains in the areas being separated, rehabilitation or relay of water mains in the areas, and associated paving costs. 9-3

10.0 PROGRAM MODIFICATIONS With the lodging of the Consent Decree in August 21012, the Commission has undertaking a number of remedial measures to improve and update its Stormwater Management Program such as outfall screening, SSO reporting and tracking, SSO Emergency Response (ERP) development, Construction Site Inspection Program development, updated its IDDE methodology and practices, set IDDE prioritization for sub-catchments, executed intergovernmental agreements and taken other actions. No formal modifications to its Stormwater Management Program were made in 2012, or are being requested at this time.

Vincent G. Mannering, Executive Director May June 2012 For a Cleaner Boston Harbor, Scoop the Poop Dog owners can help prevent contamination of local waterways, parkland, and beaches by picking up after their dogs. Dog waste should be placed in a proper trash receptacle. Never throw dog waste or rubbish into the catch basins. These catch basins are for stormwater. During rainy weather, dog waste that is not scooped is carried in stormwater runoff to catch basins. Catch basins connect to Boston s storm drain system that discharges to Boston Harbor as well as the Charles, Muddy, Mystic and Neponset Rivers. Dog waste pollutes beaches and parklands in addition to being unpleasant and unhealthy for swimmers, sunbathers, and aquatic life. The Boston Water and Sewer Commission is dedicated to improving the harbor and ensuring cleaner, more enjoyable rivers and beaches. Please help by picking up after your pet and disposing of the waste properly. Boston Water and Sewer Commission 980 Harrison Avenue, Boston, MA 02119 (617) 989-7000

Vincent G. Mannering, Executive Director Setember-October 2012 Help Reduce Environmental Pollution Properly dispose of household hazardous products. Almost every home contains hazardous products, or products that can harm human health or the environment if improperly handled. Leftover household products that contain corrosive, toxic, ignitable, or reactive ingredients are considered to be household hazardous waste (HHW). They are products used in cleaning, home improvements, automobile maintenance, lawn and garden care, hobbies, and a variety of other tasks. Some oil-based paints, cleaners, oils, batteries, tires and pesticides that contain potentially hazardous ingredients require special care when you dispose of them. Improper disposal of HHW can include pouring them down the sink, on the ground, into storm drains, or in some cases, putting them out with the trash. The dangers of such disposal methods might not be immediately obvious, but improper disposal of these materials can pollute local waterways, contaminate the ground, and pose a threat to human health. Boston residents can conveniently and safely dispose of HHW at the City of Boston Public Works Department s Hazardous Waste Drop-Off Days. For a list of acceptable household products, visit www.cityofboston.gov/publicworks/wastereduction/hazardous.asp. What s under your kitchen sink, in your garage, in your bathroom, and on the shelves in your laundry room?

Purchase rechargeable batteries to eliminate waste. Guidelines For Boston residents only; proof of residency required. No commercial waste will be accepted. Foot traffic is prohibited. The City reserves the right to reject materials. For more information, please call the Mayor s Hotline at 617-635-4500.

When recycled and composted, this yard waste is used as a natural fertilizer for Boston s community gardens. 2012 Collection Schedule will be on Recycling Days for4 weeks Guidelines Leaves, grass and twigs can be placed in paper leaf bags or open barrels labeled yard waste (no plastic bags). Yard Waste stickers for barrels are available by calling 617-635-4959. Tie branches with string, 3 ft. maximum length. Do not put branches in barrels.
