10 Part 1: Continued Plan Review Scheduled Plan Review Annual Comprehensive Compliance Evaluation (ACE) Changes in Operation 12 weeks to implement changes Plan Revisions and Additions Note on inspections Pen changes are OK Retention of Records 3 years

11 Part 2: General Facility Information Basic Site Info (name, address) Important Info (Permit #, operating hours)

12 Part 2: Continued This includes Owner/Operator information, permit information and contact information Facility Description which includes: Location and Activities Site maps Inventory of exposed materials Narrative Description of exposed material EPCRA 313 Reporting Requirements

Part 2: Continued Non-Storm Water Discharge Certification Inspections Appendix A The facilities have been inspected for the following nonemergency, non-storm water discharges: 1.

13 Part 2: Continued Non-Storm Water Discharge Certification Inspections Appendix A The facilities have been inspected for the following nonemergency, non-storm water discharges: 1. Discharge from firefighting activities & uncontaminated fire hydrant flushing; 2. Potable water sources; 3. Lawn watering and/or other irrigation drainage; 4. Water from the routine external washing of buildings without the use of detergents or chemicals; 5. Water from the routine washing of pavement conducted without the use of chemicals or detergents where there have not been spills of hazardous or toxic chemicals; 6. Uncontaminated air conditioner, compressor and steam condensate; 7. Water from foundation or footing drains when flows are not contaminated; 8. Water used for dust suppression; and 9. Springs or other uncontaminated groundwater. Spill and Leak History SPCC Plan

14 Part 3: Pollution Prevention Measures & Controls Good Housekeeping 1. Labeled containers 2. Designated storage areas for tools, equipment and supplies 3. Routine road sweeping near entry/exit 4. Litter pickup

15 Part 3: Continued Spill Prevention Reference a SPCC Plan Provide spill response procedures Maintenance Program for Structural Controls Ditches Ponds Silt Fencing Oil Water Separators

16 Part 3: Continued Erosion Control Paved/Improved entrance/exit Improved haul roads Vegetated areas Silt fencing for exposed areas Dust suppression Additional BMPs Sector specific Site specific

17 Part 3: Continued Management of Runoff Employee Training Employees with responsibilities for implementing or maintaining activities in SWPPP All others (administrative) Routine Inspections Weekly Monthly Quarterly Annual Compliance Evaluations 12 weeks to implement changes/recommendations

Part 4: General Monitoring & Reporting Requirements The TPDES MSGP requires four types of storm water monitoring: 1. Visual analysis, conducted on a quarterly basis. 2.

18 Part 4: General Monitoring & Reporting Requirements The TPDES MSGP requires four types of storm water monitoring: 1. Visual analysis, conducted on a quarterly basis. 2. Benchmark monitoring for designated constituents (which are sectorspecific), conducted semi-annually; 3. Numeric Effluent Limitation (NEL) monitoring for hazardous metals, conducted Annually, and 4. TMDL monitoring - if a TMDL exists for the receiving waters.

19 Quarterly Visual Analysis Monitoring Once per quarter Begin first full quarter following submission of the NOI 1 sample per designated outfall Substantially similar outfall can be used Reporting Retain on site SWPPP Team MUST review

20 Monitoring Semi-annual Sector specific Includes parameters like TSS Metals COD Nitrate + Nitrite Nitrogen Benchmark Monitoring Reporting To TCEQ by March 31 of the following year Form Report of Benchmark Monitoring Data Benchmark Monitoring Exceedances DOES NOT constitute a permit violation DOES indicate a deficiency in SWPPP Requires SWPPP Team to investigate and document results within 90 days.

22 Numeric Effluent Limitation (NEL) Monitoring Monitoring Conduct annually for each designated outfall 12 Texas metals May be waived

23 Reporting Numeric Effluent Limitation (NEL) Monitoring (Cont) Discharge Monitoring Report Submit only if exceedances, otherwise retain on site Submit by: March 31 of following year; or Within 5 days if exceedance was > 40% of NEL

25 Numeric Effluent Limitation (NEL) Monitoring (Cont) NEL Monitoring Exceedances DO constitute a permit violation. REQUIRES a review of SWPPP and modification within 90 days

26 NEL Monitoring Waivers A waiver from NEL monitoring can be obtained on a metal by metal or outfall by outfall basis IF one or more of the following conditions are met and certified in writing: The permittee certifies that the regulated facility does not use a raw material, produce an intermediate product or produce a final product that contains one or more of the identified hazardous metals; or The permittee certifies that any raw materials, intermediate or final products which contain a hazardous metal are not exposed to storm water; or The permittee collects a sample of the discharge, conducts the analysis of the sample and the results indicate that the metal(s) is /are not present in detectable levels.

27 Storm Water Sampling Representative Storm Events 0.1 inches Preceded by 72 hours of dry weather (no discharge) Occurs during normal operating and daylight hours The Permit requires a rain gauge to be maintained on site. Rain gauge records must be maintained on site.

28 Representative Discharge for Substantially Similar Outfalls If the facility has a discharge that is expected to be substantially identical to other discharges based on the industrial activity in those drainage areas, one discharge can be sampled, and the results reported for both discharges.

29 Monitoring Periods Monitoring periods set forth by the MSGP: Quarterly (Visual) Q1: January March Q2: April June Q3: July September Q4: October December Semi-Annual (Benchmark) P1: January June P2: July December Annual (NEL) January 1 st December 31 st

30 Temporary Suspension and Waivers Temporary Suspension Adverse weather conditions (flooding, high winds, tornados, electrical storms, drought or extended frozen conditions) Rainfall amounts outside of daylight/normal operating hours Must be conducted in the next designated monitoring period, along with the required events for that period

31 Temporary Suspension and Waivers (Cont) Waivers If the temporarily suspended sampling event cannot be collected during the subsequent sampling period then it may be permanently waived and is not required.

32 Additional Monitoring If sampling/monitoring is conducted more frequently than that required by the permit and outlined in this SWPPP, then the results of ALL sampling/monitoring must be recorded and reported as required. Reporting 30 TAC requires any non-compliance which may endanger human health, safety, or the environment to be reported to the TCEQ. Provide to the TCEQ Regional Office orally or via fax within 24 hours of becoming aware of the non-compliance. A written report must be provided to the TCEQ Regional Office and TCEQ Enforcement Division (MC-224) within five (5) days of becoming aware of the non-compliance.

Part 5: Sector Specific Requirement May Include: Chemical sampling requirements (Timber Product Facilities Sector A) Benchmark monitoring requirements (TSS, COD, total Zinc) Spill prevention and

33 Part 5: Sector Specific Requirement May Include: Chemical sampling requirements (Timber Product Facilities Sector A) Benchmark monitoring requirements (TSS, COD, total Zinc) Spill prevention and response measures - (Land Transportation Sector P) Vehicles and equipment with potential leaks and scheduled for maintenance must be confined to a designated area Additional inspection Requirements (Water Transportation Facilities Sector Q) Pressure washing areas, dry docks, engine maintenance/repair areas

34 Part 6: NOI & Permit Documentation Notice Of Intent TPDES Permit Certificate/Permit number

35 Part 7:TPDES MSGP TXR05000 TPDES MSGP TXR05000 A copy of the permit must be included in your SWPPP
