Narrative of MS4 2. Incorporate GI/LID/ESD into municipal infrastructure upgrades 3. Estimate current pollutant loads (optional) 4. Identify TMDL control measures PA DEP Document 3800-FM-BPNPSM0493 8/20/13

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 8 Step 1. Narrative of MS4 Drainage area of MS4 within the UA discharging to the Chesapeake Bay Watershed: 1. Pervious and impervious cover (%) 2. Land use (acres) 3. Stream miles (note impaired streams) (linear feet) *Sources of GIS data included on resource sheet

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Step 1. Narrative of MS4 • Other information to include: – Areas not included • Large federal facilities (not responsible for) • Other permitted entities – Watersheds and tributary streams in MS4 – High quality areas – Protected lands – Population stats – Other relevant information 12

Incorporate GI/LID/ESD into municipal infrastructure upgrades 3. Estimate current pollutant loads (optional) 4. Identify TMDL control measures

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 15 Step 2. Incorporate GI/LID/ESD into Municipal Infrastructure Upgrades • Green Infrastructure (GI) • Low Impact Development (LID) • Environmental Site Design (ESD)

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 16 Step 2. Incorporate GI/LID/ESD into Municipal Infrastructure Upgrades

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 17 Step 2. Incorporate GI/LID/ESD into Municipal Infrastructure Upgrades

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan • Example I – Street Widening project on Main Street • Options Considered – Bioretention – Porous Pavement • Considerations – On-street Parking – Mature Trees • Result – Neither option is feasible here because most residences do not have driveways and loss of parking for street scape bioretention is not acceptable to community. – Potential damage to large mature trees during construction and concerns of clogging due to leaf litter result in porous pavement being unacceptable. 18

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan • Example II – New Township Park • Options Considered – Bioretention in parking lot – Stream restoration with floodplain connection and forest buffer • Considerations – Costs – Permits – Construction timeline • Result – Bioretention will be implemented along the down slope perimeter of the parking lot as well as in the parking lot islands – Stream restoration will occur in phases with phase 1 occurring at the time of park development and phases 2 and 3 occurring in subsequent years. 19

Incorporate green infrastructure into municipal infrastructure upgrades 3. Estimate current pollutant loads (optional) 4. Identify TMDL control measures

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 21 Step 3. (Optional) Estimate Current Pollutant Loads Benefits: 1. Provide a baseline pollutant load for your municipality 2. Account for what you and your partners (watershed groups, schools, etc) have done 3. Have a better understanding of current rate of progress.

(Optional) Estimate Current Pollutant Loads  Modeling programs  MapSheds (GWLF)- PSU  www.mapshed.psu.edu/  Chesapeake Assessment and Scenario Tool (CAST)- CBP  www.casttool.org  Others  Watershed Treatment Model  http://www.cwp.org/online-watershed-library/  See CBF webcast on modeling

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Data requirements • Minimum – BMP type and acres treated (or area for land-use change BMPs) • Better – BMP type, acres treated and % impervious • Best – BMP type, acres treated, % impervious, land use type, and amount of runoff retention (i.e. 1”, 2.5”, etc.) 23

PA Municipal Separate Storm Sewer System (MS4) TMDL Plan Chesapeake Bay Pollution Reduction Plan 28 Step 4. Identify TMDL Control Measures Identify TMDL control measures and include: 1. Location of BMPs (latitude/longitude, street name, other) 2. Implementation schedule including interim milestones 3. BMP pollutant reduction for N, P and/or Sediment 4. Rationale for selecting the BMP 5. BMP Inspection, operation and maintenance
