Stormwater ≠ Stormwater Management • “Stormwater” ≠ “Stormwater Management” • Act 167 - • Section 3, Purpose and Policy, preservation of natural storm water runoff regimes, groundwater and groundwater recharge areas • Section 4, “Stormwater.” Drainage runoff from the surface of the land … • Runoff, evaporation, infiltration, storage, and reuse are affected • “Stormwater Management” can affect the entire supply of fresh water?
WHEN IT RAINS… • Pennsylvania is one of the most flood-prone states in the nation. - PEMA • World Record 4.5-Hour Rainfall • 30.8 inches, July 18, 1942, Smethport - NOAA • National Records • 16 inches, 3 hours, August 5, 1843, Concord, Franklin Co. • 34.5 inches, 24 hours, July 17-18, 1942, Smethport
Effect of Development on Stormwater Runoff w/o management Pre-development w/ management Even 1% increased impervious area within a watershed can result in significantly increased volume & runoff rate, if left unmanaged.

Storm Water Management • DEP’s Permitting and Grant Programs must comply with the State Water Quality Standards, including • NPDES Storm Water Discharges from Construction • NPDES Phase II MS4 Permits (Urban Areas) • Act 167 Storm Water Management Plans • Dam Safety and Waterway Management (25 Pa.Code Chapter 105) • Post construction storm water impacts must comply with • Pennsylvania Water Quality Standards25 Pa. Code Chapter 93
23 Pa.Code §93.4aANTIDEGRADATION REQUIREMENTS § 93.4a. Antidegradation. (a) Scope. This section applies to surface waters of this Commonwealth. (b) Existing use protection for surface waters. Existing instream water uses and the level of water quality necessary to protect the existing uses shall be maintained and protected. (c) Protection for High Quality Waters—The water quality of High Quality Waters shall be maintained and protected, except as provided in § 93.4c(b)(1)(iii) (relating to implementation of antidegradation requirements). (d) Protection for Exceptional Value Waters—The water quality of Exceptional Value Waters shall be maintained and protected.
Chesapeake Bay – PA Goals by 2010 • Watershed plans covering 2/3 of tributary area (9.6 million acres). • Objectives are protection, conservation and restoration of stream corridors, riparian forest buffers and wetlands. • Wetland preservation plan covering 3.6 million acres restore 4,000 acres.
Chesapeake Bay Watershed • 43 counties have land area in the Chesapeake watershed • 36 have participated in Act 167 stormwater management planning • 21 are actively involved in county-wide Act 167 stormwater management planning
Some of the Reasons for Storm Water Management Planning • Protection of water quality requires control of storm water discharge rates, volumes, and quality. • Amount of pollutant Volume of runoff. • Land development and land alteration change the amount and characteristics of stormwater runoff. • Changing land use from forest to impervious can • Increase runoff volume 5x to 7x(50% ET, 33% GW, 17% RO) • Increase peak rate of flow 4x (typical) • Changes in runoff rates, volumes, and quality affect property, safety, health, and the environment. • Siltation is involved in 51% of PA’s impaired stream miles. • Land development in many counties is projected to continue at a rapid pace –increasing stresses and demands on water resources.
Stormwater Management Act 1978 Act 167 A Good Program Model - Do More With It! V Integrated Water Resources Planning
Pennsylvania Stormwater Management Act Counties: Prepare Plans Municipalities: Implement Plans DEP: Assistance, Administration, Consistency, … 14
Act 167 Framework - 1 Act 167 is a planning program that runs on three governmental powers • Governmental powers of municipalities to • implement programs via local ordinances, • Administer, manage, regulate, and enforce stormwater control ordinances, • Land use controls: zoning, subdivision and development, • Building codes, • Erosion and sediment control, • Public nuisance, • Raise money.
Act 167 Framework – 2-3 • Planning power and capacity of counties to prepare county-wide and watershed-based plans for each county. • DEP’s power to administer, coordinate, and support the planning process by providing • Consistent statewide implementation of the program. • Financial and technical assistance to counties and municipalitiesDEP covers 75% of allowable costs. • Guidelines. • Model Ordinance. • Other support.
Stormwater Management ActLegislative Findings The General Assembly finds that: (1) Inadequate management of accelerated runoff of storm water resulting from development throughout a watershed increases flood flows and velocities, contributes to erosion and sedimentation, overtaxes the carrying capacity of streams and storm sewers, greatly increases the cost of public facilities to carry and control storm water, undermines flood plain management and flood control efforts in downstream communities, reduces ground-water recharge, and threatens public health and safety. (2) A comprehensive program of storm water management, including reasonable regulation of development and activities causing accelerated runoff, is fundamental to the public health, safety and welfare and the protection of the people of the Commonwealth, their resources and the environment.
Stormwater Management Act Purpose and Policy Section 3. Purpose and policy. The policy and purpose of this act is to: (1) Encourage planning and management of storm water runoff in each watershed which is consistent with sound water and land use practices. (2) Authorize a comprehensive program of storm water management designated to preserve and restore the flood carrying capacity of Commonwealth streams; to preserve to the maximum extent practicable natural storm water runoff regimes and natural course, current and cross-section of water of the Commonwealth; and to protect and conserve ground waters and ground-water recharge areas. (3) Encourage local administration and management of storm water consistent with the Commonwealth's duty as trustee of natural resources and the people's constitutional right to the preservation of natural, economic, scenic, aesthetic, recreational and historic values of the environment.
Act 167 Requirement to Prepare Plans Section 5. Watershed storm water plans and contents. (a) Within two years following the promulgation of guidelines [May 14, 1985] by the department pursuant to Section 14, each county shall prepare and adopt a watershed storm water management plan for each watershed located in the county as designated by the department, in consultation with the municipalities located within each watershed, and shall periodically review and revise such plan at least every five years. The department may, for good cause shown, grant an extension of time to any county for the preparation and adoption of a watershed storm water management plan.
Enforcement of Plan Preparation Section 7. Joint plans and coordination of planning. Where a watershed includes land in more than one county, the department may require the affected counties to prepare, adopt and submit a joint plan for the entire watershed. Section 10. Failure to submit plan; mandamus. The department may institute an action in mandamus to compel counties to adopt and submit plans in accordance with this act. (10 repealed in part Oct. 5, 1980, P.L.693, No. 142 and repealed insofar as inconsistent Oct. 15, 1980, P.L.950, No. 164)
Effect of Act 167 Plans Section 11. Effect of watershed storm water plans. (a) After adoption and approval of a watershed storm water plan in accordance with this act, the location, design and construction within the watershed of storm water management systems, obstructions, flood control projects, subdivisions and major land developments, highways and transportation facilities, facilities for the provision of public utility services and facilities owned or financed in whole or in part by funds from the Commonwealth shall be conducted in a manner consistent with the watershed storm water plan.
Effect of Act 167 Plans Section 11. Effect of watershed storm water plans. (b) Within six months following adoption and approval of the watershed storm water plan, each municipality shall adopt or amend, and shall implement such ordinances and regulations, including zoning, subdivision and development, building code, and erosion and sedimentation ordinances, as are necessary to regulate development within the municipality in a manner consistent with the applicable watershed storm water plan and the provisions of this act.
Duties of Persons Section 13. Any landowner and any person engaged in the alteration or development of land which may affect storm water runoff characteristics shall implement such measures consistent with the provisions of the applicable watershed storm water plan as are reasonably necessary to prevent injury to health, safety or other property. Such measures shall include such actions as are required: (1) to assure that the maximum rate of storm water runoff is no greater after development than prior to development activities; or (2) to manage the quantity, velocity and direction of resulting storm water runoff in a manner which otherwise adequately protects health and property from possible injury.
