    DRAFT COUNTY-WIDE ACT 167 STORMWATER MANAGEMENT PLAN
    (8/13/12 VERSION)

    Overview


    Chester County is required by PA Act 167 Stormwater Management Plan Act of 1978 to prepare a stormwater management plan for all of Chester County's watersheds. The response from municipalities regarding the concept of using a county-wide approach to fulfill the PA Act 167 requirements was favorable, so a County-wide 167 Plan is now underway for the entire area of Chester County and all of its watersheds. The County-wide 167 Plan will be based on and will incorporate Chester County's Watersheds Plan, and will include key provisions from Act 167 plans that were previously approved for individual watersheds.
     
    The County-wide 167 Plan is being prepared by CCWRA, in conjunction with the Chester County Planning Commission and the Chester County Conservation District. Throughout the County-wide 167 Plan process, extensive feedback has been collected from municipalities and stakeholders through numerous meetings, municipal questionnaires, and review comments on draft documents, and that feedback has been incorporated into the plan documents.
     
    Municipalities across Chester County are experiencing flooding, stormwater management and/or stormwater pollution problems. Approximately 25% of Chester County's streams are polluted, primarily from stormwater pollutant runoff and stream channel erosion from increased stormwater discharges. Many of Chester County's municipalities are also faced with federal and state stormwater management and water quality regulatory requirements that are complex and difficult to implement.
     
    The County-wide 167 Plan is being prepared to assist municipalities in addressing these issues. The Plan will help to reduce future flooding and stormwater impacts and to improve and protect the water quality of Chester County's streams. It will also assist municipalities in addressing stormwater management needs and certain NPDES MS4 regulatory requirements.
     
    The County-wide Act 167 Plan will be comprised of the Watersheds Plan (as published 2002) with an Act 167 Addendum. The Addendum will include a Model Ordinance and Standards Matrix for stormwater management related to land disturbance, Christina Basin MS4 TMDL Implementation Strategy, Act 167 Plan consistency requirements for state financed projects, and additional documentation required to fulfill the Act 167 plan requirements.
