5 Why regulate Stormwater?

10 Pollution Pollution P O2 depletion Sediment N Algal bloom Shading Clean Water Shading Impacts Aquatic organisms Human health Human use and enjoyment of the environment

11 Concentrations of nitrogen and phosphorus in natural waters, Stormwater and wastewater (expressed in mg/L) ** current technology Note that untreated urban stormwater runoff has about the same concentration as treated wastewater Parameter Natural Waters Urban Stormwater Untreated sewage CSOs Treated sewage** Nitrogen 0.1(as NO-3) 2 to 3 20 3-24 3 Phosphorus 0.005 –0.05 (as dissolved P) 0.2 –0.5 10 1-11 0.1

12 Runoff Event Mean Concentrations (EMCs) for N and P in an Urban Environment
Urban Land Cover Total N (mg/l) Total P (mg/l) Lawns 9.70 1.90 Highway 2.95 0.60 Streets 1.40 0.50 Parking lots 1.94 0.16 Roof tops 1.50 0.12 Source: CWP, 2003

13 Urban Nutrient Loads (are fast becoming a bigger slice of the Bay pie)
Year Total N Total P % 5% % % % 22% ???? Urban and suburban runoff into the Chesapeake Bay is the only nutrient load sector where we are seeing reverse progress In load reductions-source OIG (2007)

14 There are many sources of N and P in the urban environment

15 Some additional sources of nitrogen in urban runoff include:
Wash-off of fertilizers Nitrogen attached to eroded soils and streambanks Organic matter and pet wastes on Impervious Cover

16 Effect of Eutrophication on Waters
Increased frequency of algal blooms Increased hypoxia and anoxia Decline in submersed aquatic plants Reduced water clarity Decline in benthic life Fish kills

17 Nutrient Enrichment by Stormwater
Most streams have a naturally low phosphorus content (TP) EPA’s recommendation for TP in natural streams is 0.1 mg/l P-enriched streams have: higher biomass less biological diversity more bottom algae and rock scum lower oxygen levels

18 Impact of development on stream quality

19 Stream Impacts 8-10% 20% > 65% Impervious Cover
In-stream erosion results in the release of nutrients into the stream. These nutrients are/were attached to soil particles and in pore spaces.

20 Pollution of 1970s The Federal Pollution Control Act of 1972  NPDES
Clean Water Act (1977) NEPA (1970) Clean Air Act (1970) ESA (1973) TSCA (1976) CERCLA (1980)

21 Governor’s Natural Resources Partnership Agenda
“The Secretary of Natural Resources will work with the DEQ, DCR, CBLAD, other agencies and the public to streamline the current storm water management process. A plan and recommendations are due to the Governor by October 1, 2003 that provides for improved water quality protection and evaluates stormwater programs statewide.”

22 Some of the Key Recommendations
Establish a more uniform statewide construction permitting program Establish statewide stormwater requirements for projects with land disturbances of 1 acre or greater (with allowance for lower threshold in CBPA) Empower local governments to implement stormwater management programs Develop a statewide permit fee system Encourage low-impact approaches and better site designs Consolidate SWM and ESC local program reviews

23 2004 Legislation Followed a year of planning meetings/negotiations among Secretary of Natural Resources, three agency heads and key program staff Accomplished most of Partnership Agenda SWM objectives Moved nearly all SWM responsibilities from DEQ and CBLAD to DCR, effective July 1, 2004 DEQ retained responsibility for issuing industrial SWM permits

24 2004: Beginning of Stormwater Management in Virginia
Since 2004 Stormwater quality and quantity management are mandatory throughout Virginia

25 Impact of the 2004 Legislation on Clean Water Act Implementation in Virginia
DEQ DCR Wetlands E&S NPDES Industrial Facilities VSMP Wastewater Treatment Plants MS4 TMDL Construction General Permits Non Point-Source Nutrient Management Chesapeake Bay Local Assistance

26 Implementation The Soil and Water Conservation Board passed a motion on July 21, 2005 authorizing the development of a Notice of Intended Regulatory Action (NOIRA). With significant stakeholder involvement, completed regulation revision in two separate regulatory actions Part 13-Fees, effective February 3, 2010 Parts 1, 2 and 3-Definitions, Technical Criteria and Local Programs, effective September 13, 2011 Included delayed implementation and grandfathered sections to establish stormwater programs.

27 Issues encountered during the development of the 2011 Virginia Stormwater Regulations:
Highlighted inconsistencies and contradictions between the CBA, VESCL, VSMA Difference between localities located in the Chesapeake Bay watershed and those that are not No good guidance on training and certification

28 House Bill 1065 (Integration Bill)
Amends the Erosion and Sediment Control Law, the Stormwater Management Act and the Chesapeake Bay Act to remove inconsistencies and contradictions between the three laws.

29 What the Integration Bill does:
Makes the definition section consistent across the three acts Requires all counties cities and towns that are MS4s in Virginia to adopt a VSMP program Allows non MS4 towns to adopt a program or be subject to the program of the county where the town is located

30 What the Integration Bill does:
Requires that you have an approved E&S plan and coverage under VSMP before land disturbance can take place Establishes a VSMP and VESCP Eliminates the Chesapeake Bay Local Assistance Board and transfers oversight of the Chesapeake Bay Preservation Act to the Virginia Soil and Water Conservation Board

31 What the Integration Bill does not do:
It does not change any of the CBPA requirements (does not eliminate the need to comply with the act) It does not make the CBPA applicable statewide It does not change the area (localities) that the original CBPA applies to

32 What the Integration Bill does not do:
Separate approved E&S plans and the Stormwater Permits are still required before starting land disturbance (more than one approval required) There are still different permit thresholds for an E&S plan (10,000 and 2,500 sf) and a Stormwater Permit (1 acre)

33 The SWA (after HB1065) 10.1-603.2 Definitions

The SWA (after HB1065) (some important changes to the Act)

35 The SWA (after HB 1065) In the Definitions (§ ) defines: Chesapeake Bay Preservation Act land-disturbing activity as “land-disturbing activity … that result in a land disturbance equal or greater than 2,500 square feet and less than one acre in all areas of jurisdiction designates as subject to the regulations adopted pursuant to the Chesapeake Bay Preservation Act.”

36 The SWA (after HB 1065) In the Definitions (§ ) defines: Virginia Stormwater Program or VSMP as “a program approved by the Board after September 13, 2011, that has been established by a VSMP authority to manage the quality and quantity of runoff resulting from land-disturbing activities …”

37 The SWA (after HB 1065) In the Definitions (§ ) defines: Virginia Stormwater Program authority or VSMP authority include localities, state entities. Federal entities, and “linear project companies.”

38 The SWA (after HB 1065) In the Definitions (§ ) defines: Watershed … “In karst areas, the karst feature to which water drains may be considered the single outlet for the watershed.”

39 § 10.1-603.3 Establishment of VSMPs
