4 MCM#3 BMP: Map all outfalls and receiving water-bodies

6 Where to Begin

7 Data Collection Key Terms Outfall -A point source as defined by 40 CFR at the point where a municipal separate storm sewer discharges to waters of the United States and does not include open conveyances connecting two municipal separate storm sewers, or pipes, tunnels or other conveyances which connect segments of the same stream or other waters of the United States and are used to convey waters of the United States. Point Source - any discernable, confined and discrete conveyance, including but not limited to any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, vessel, or other floating craft from which pollutants are or may be discharged.

or pipes, tunnels or other conveyances which connect segments of the same stream or other waters of the United States and are used to convey waters of the United States.

8 Data Collection Key Terms Pollutant - dredged spoil, solid waste, incinerator residue, filter backwash, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials (except those regulated under the Atomic Energy Act of 1954, as amended (42 U.S.C et seq.)), heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal, and agricultural waste discharged into water.

(except those regulated under the Atomic Energy Act of 1954, as amended (42 U.S.C. 2011 et seq.

13 Data Collection Collecting Outfall Data

14 Data Collection Collecting Outfall Data We utilized our Township Engineer, RAV Associates to collect the data for the outfalls. They collected location and site condition data on 353 outfalls. They then created data points for each outfall. They numbered each outfall. They filled out a field sheet for each outfall.

They collected location and site condition data on 353 outfalls.

16 Data Collection Outfall Map Next, we created a map showing all the outfalls. This included data such as site number, type of structure, and if it is a dry weather flow. A dry weather flow is an outfall that has water flowing when there has been no rain for at least three days.

17 Data Collection Outfall Map What Should My Map Look Like? Understanding the location of your separate storm sewer system outfalls is the key to effectively managing stormwater runoff and protecting water quality. Not all system maps will look alike, but they should contain the same basic information and ultimately serve as a tool for your employees responsible for implementing the IDD&E Program (Illicit Discharge Detection & Elimination), as well as other components of the Stormwater Management Program. SCALE. The map must be of a scale that shows street-level detail and extends beyond the service boundaries of the municipal storm sewer system. A scale between 1:10,000 and 1:25,000 may be appropriate for many small MS4s that cover a large land area. This scale is acceptable as long as street-level detail can be obtained. Otherwise you should use a map scale that best depicts specific location information for each outfall, as technicians in the field will need street-level detail in order to effectively locate and monitor outfalls.

18 Data Collection Outfall Map SYSTEM FEATURES. The goal of the system mapping is to identify all outfalls and the name/location of the receiving water bodies, to support an effort to detect and eliminate illicit discharges. FORMAT. Only you can determine what format is best for your community. Factors such as staff, money, format of available data and equipment will dictate how you generate your system map. You may wish to use a geographic information system (GIS) to electronically generate your system map. PA DEP recognizes that not all communities have GIS capabilities. For those that do not have GIS capabilities, you can generate your map using other means. The format of your map is not as important as the quality of the information it contains. For help with developing your system map, consult the list of resources provided in Appendix 1.

22 Data Collection Collecting BMP Data Next Step in the process was collecting the BMP data. We were able to hire a summer intern from Millersville University to help with the Data Collection. We began by pulling together a list of all the Land Development Plans that were recorded within the designated time period.

23 Data Collection Collecting BMP Data We developed an Excel Table to track the data. Data included Parcel Number, Plan Number, Location of File, and Plan Name Parc_Numb Plan_Numb Stor_Loc Plan_Name FP Box_62 CFC FP Box_73 Hassel_Tract FP SALDO Brub_BP RFP Filing_Cab Nool_L_ FLD SALDO FP Filing_Cab SKH FLD Box_25 Regen_Sq FP Filing_Cab Hayden_Mnr FLD SALDO Mear_Kia FLD SALDO Lacn_Toy FP Filing_Cab Gold_Mead_P FLD Box_79 St_Edwards FP SALDO Winde_Pl FP Filing_Cab HSD FP Filing_Cab Hemp_Cross FLD Filing_Cab Union_Natl FLD SALDO LASA FLD Box_31 BJs FLD Filing_Cab SHEETZ FLD/ FP Filing_Cab The_Arbors FP/03-41-FP SALDO Vill_Grande FP Box_74 Porter_Trt

32 Data Collection Collecting BMP Data Next steps is taking samples of dry weather flows. To do this we use the GPS to locate the outfalls. Photos are taken at each location and attached to the record. A file is kept for record keeping and any needed follow-up.
