The Permit Program • WHO? • Operators of a storm sewer system • WHERE? • “Urbanized areas” • Designated by EPA or DEP • Petitions and waivers • HOW? • BMPs for water quality protection • Use of statewide programs
Why this new program in Pennsylvania? • Evolution of water pollution priorities nationwide • Industrial operations, sewage treatment • “…maintain the chemical physical, and biological integrity…” • urban areas impervious cover, etc. • Federal regulations • 1987 Clean Water Act amendments • EPA regulations in phases: 1990, 1999 • 40 CFR 122.26
Basic Permitting Approach • WHO? • Operators of a storm sewer system • WHERE? • “Urbanized areas” • Designated by EPA or DEP • Petitions and waivers • HOW? • BMPs for water quality protection • Use of statewide programs
Who Must Get a Permit? “Municipal Separate Storm Sewer System (MS4)” • System of conveyances – roads, swales, drainage systems • Used for collecting/conveying stormwater • Owned or operated by public body • Operator must get the permit
Basic Permitting Approach • WHO? • Operators of a storm sewer system • WHERE? • “Urbanized areas” • Designated by EPA or DEP • Petitions and waivers • HOW? • BMPs for water quality protection • Use of statewide programs
WHERE does this apply? • “Urbanized Areas” • Bureau of Census draws the boundaries • Designated by EPA or DEP • Listed in Federal Register, along with MS4s and • MS4s outside of UAs which meet population/density criteria or • Physically interconnected • Petitions • MS4 interconnected systems, CSOs • Any person discharge which contributes to pollution • Waivers • Small MS4s

Basic Permitting Approach • WHO? • Operators of a storm sewer system • WHERE? • “Urbanized areas” • Designated by EPA or DEP • Petitions and waivers • HOW? • Municipal Program – 6 Elements • Use of statewide programs
What is Required? • Stormwater program - 6 Elements • Public Education • Public Participation & Involvement • Illicit Discharges • Construction • Post-construction • Pollution prevention/good housekeeping
What is a BMP? • for post-construction…. • “non-structural” • Ordinance • Policies for inspections • Open space design criteria • “structural” • Wet ponds • Infiltration basins • for illicit discharges …. • Establish “priority areas,” take corrective actions, education
Basic Permitting Approach • WHO? • Operators of a storm sewer system • WHERE? • “Urbanized areas” • Designated by EPA or DEP • Petitions and waivers • HOW? • Municipal Program – 6 Elements • Use of statewide programs
State-wide programs which can be used • Erosion and Sediment Control (“Chapter 102”) & NPDES Storm Water Construction Permits • NPDES permit revisions to address post-construction • Storm Water Management Act (“Act 167”)
Act 167 Stormwater Management Act • Basic Process: • County does the plan • with involvement of municipalities • In consultation with DEP • DEP provides technical oversight, approves plan • Municipalities implement through ordinance • Developers follow requirements in plan -- BMPs
Act 167 Stormwater Management Act • Enacted in 1978 – program focus has been on flooding (“peak flow attenuation”) • Water quality focus added in 2001 • Watershed-based, multi-municipal participation • Allows 75% cost-share funding for stormwater management in counties and municipalities • Planning and implementation • Authorizes funding for all 6 elements required under federal MS4 regs
What is Required? • Stormwater Program - 6 Elements • Public Education • Public Participation & Involvement • Illicit Discharges • Construction • Post-construction • Pollution prevention/good housekeeping
MS4 General Permit Proposal(PAG-13) • MS4s have two options: • Follow DEP “Stormwater Management Protocol” • Commit to Act 167--watershed-based, multi-municipal • “Pre-approved” • Up to 75% cost-share funding • Relaxed deadlines Or • Develop own program • Must get DEP approval • Ineligible for funding under Act 167
What is Required? • Stormwater Program – 6 Elements • Public Education • Public Participation & Involvement • Illicit Discharges • Construction • Post-construction • Pollution prevention/good housekeeping
DEP’s Proposed “Protocol” • Construction and Post-Construction • No building permits in municipality until • Approved E&S plan (and if needed, NPDES Construction Permit (revised)) • Approved post-construction plan • Follow Act 167 requirements (where applicable) • Generates watershed-specific standards for post-construction protection of water quality
Post Construction and Water Quality Standards • maintain the chemical, physical and biological integrity (federal and state law) • Anti-degradation requirements – Section 93.4a • Considerations • Infiltration and base flow • Pollutants in runoff • Channel protection
What is Required? • Stormwater Program – 6 Elements • Public Education • Public Participation & Involvement • Illicit Discharges • Construction • Post-construction • Pollution prevention/good housekeeping
MS4 General Permit Proposal • Illicit Discharges • System mapping--outfalls • Ordinance—set the legal standard • Education—get the word out • Program—find the illegal discharges, eliminate them
Model Ordinance • No building permits or land development approvals until SW addressed • Construction • Post-construction • Non-stormwater discharges prohibited • Penalties and enforcement
What is Required? • Stormwater Program – 6 Elements • Public Education • Public Participation & Involvement • Illicit Discharges • Construction • Post-construction • Pollution prevention/good housekeeping
MS4 Permitting—What’s Next • On-going public outreach sessions • PAG-13 finalized • Individual permit documents will be similar • Model Ordinance proposed in October • Permit applications must be submitted by March 10, 2003
