CESSWI- Sections 1 + 2 questions with correct answers Qualified Personnel a person knowledgeable in the principles and practice of erosion and sediment controls who possesses the skills to assess conditions at the construction site that could impact storm water quality and to assess the effectiveness of any sediment and erosion control measures selected to control the quality of storm water discharges from the construction acitivities How must the inspector act? professional, impartial, courteous, consistent in every situation, honest and accurate with your response Why was the CWA enacted? To restore and maintain the chemical, physical and biological integrity of the waters of the U.S. Section 401 If you are involved in construction or industrial activities that may result in discharge of any pollutant you must obtain Water Quality Certification NPDES National Pollutant Discharge Elimination System, est. 1972 Section 402 Stated that five categories of strormwater discharges were subjected to permitting Phase I facilities 1987 -those already covered under NPDES -those that engage in industrial activity -large (<250,000) municipal separate storm drain system -medium (>100,000, <250,000) municipal separate storm drain system -facilities that EPA determines to have stormwater discharges contributing to violation of water quality When did IGP and CGP roll out? 1992 Phase II dischargers -"light" industrial facilities -small construction sites (<5 acres) -small municipalities (<100,000 population) Section 404 established a permit program to regulate the discharge of dredged fill material into waters of the U.S. Stormwater is, as defined under EPA's NPDES rules,... stormwater runoff, snow melt runoff, and surface runoff or drainage Waters of the U.S. -all waters that are/were used or may be susceptible to use in interstate or foreign commerce -all interstate waters including wetlands -all other waters such as lakes, rivers, streams, mudflats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds -all impoundments of waters otherwise defined as waters of the U.S. -tributaries of waters -the territorial sea -wetlands adjacent to waters identified in this definition NOI must be filed by... "operator"- person that has day-to-day supervision and control of activities occurring at a site (may be owner/contractor) Who is exempt under Phase II? agriculture (only for crop production), O + G, and forestry What does Phase II rule require? Operators of Phase II construction sites to obtain an NPDES permit Construction rainfall erosivity waiver (only for Phase II) -low prediction rainfall potential (i.e. activity occurs in summer) -determination that stormwater controls are not necessary because TMDL addresses pollutant of concern or non-impaired waters that don't require TMDLs Who are waivers not available to? Any construction activity disturbing 5 acres or greater, or less than five acres if part of a common plan of development or sale What are beneficial uses of water? Uses of water necessary for the survival or well-being of man, plants, and wildlife (i.e. drinking, swimming, industrial and agricultural water supply, and support of fresh and saline aquatic habitats) Section 303(d) Established TMDL process to guide application of state water quality standards to individual water bodies and watersheds TMDL... defines the amount of a particular pollutant that a water body can assimilate on a daily basis without violating applicable water quality standards. Once determined, agency allocates a portion to each source of that pollutant within a particular watershed. Steps of TMDL process: -state must create list of water bodies that aren't expected to meet water quality standards -state must prioritize watersheds and target high priority watersheds for TMDL development -state must develop TMDLs Two types of permits under NPDES: -general (CGP, IGP, multi-sector general permit for industrial activities)
