Construction, post construction, industrial, MS4 Clean Water Act year of creation and intent of law 1972, enacted to restore and maintain the physical, bio, chem integrity of the waters of the US CWA Section 402 Est. NPDES System, originally focused on industrial process waste water and POTW CWA Section 404 regulated impacts to waters of the US, typically associated with a 401 certification CWA Section 401 Regulates water quality impacts and state cert systems, required permit issued by a federal agency for any activity that may discharge a pollutant, Applies heavily in industrial sites CWA Section 303 Establishes Water quality standards Stormwater discharge definition stormwater runoff, snow melt runoff, and surface runoff/drainage To be subject to NPDES rules, stormwater must: be in a discernible conveyance Definitions of waters of the US All waters used in interstate or foreign commerce, including those subject to tidal flows o All interstate waters, including interstate wetlands o All INTRAstate lakes, rivers, streams (intermittent also), mudflats, sand flats, wetlands, sloughs, prairie potholes, wet meadows, playa lake, or natural ponds that the destruction of which would affect interstate/foreign commerce including those which: Could be used for recreational or other purposes From which shellfish or fish could be retrieved and sold Could be used for industrial purposes o All impoundments of water defined by waters of the US by the above o Tributaries of the waters defined above o The territorial sea o Wetlands adjacent to any of the waters defined above Beneficial Uses definition Uses necessary for the survival of and well-being of people, plants, and wildlife Water quality standards definition state or tribal requirements that define the water quality goals of a lake stream or other wateerbody by designation the benefical uses and setting criteria to protect those uses Section 303d est a process for states, territories, and tribes to i.d. impaired waters, also referred to as water quality limited TMDL id's the amount of a specific pollutnant that may be dicharged to a water body, states are responsible for implementing Waste load allocations allocations of pollutant loadings to point sources TMDL Implementation • Threatened and endangered species assessment • Projects may qualify for rainfall erosivity waiver Types of Permitting Authority • NPDES states with general permitting authority • NPDES states with individual permitting authority • NPDES states with both general and individual permitting authority State-Specific Requirements • The states that have NPDES authority include their state-specific requirements in the general permits. • Individual permits can also contain state requirements within the individual (site-specific) permits • State requirements must be at least as stringent as federal requirements U.S. EPA has three types of enforcement: • Administrative orders • Civil actions • Criminal prosecutions Notice of Violation (NOV) Common causes NOVs: • Inadequate inspection reports • Failure to implement the SWPPP (BMPs) • Corrective actions not implemented • Sediment-laden or polluted discharges Administrative Orders • U.S. EPA can impose fines and penalties without court action Civil Penalties • U.S. EPA may bring civil suit without administrative order • Maximum penalty is $37,500 per violation (per day) with no upper limit Precon Meeting Objectives • Clarify the stormwater objectives • Designate a contact person • Determine if the SWPPP will work for the schedule, and work activities • Ensure everyone reviews the SWPPP • Remind everyone that BMPs are performance based and could require change • Conduct meeting onsite • Verify schedules... clearing, grading, stabilization, operational activities, etc. • Discuss maintenance requirements for controls identified in SWPPP • Discuss containment, storage and spill procedures of on-site pollutants • Establish open communication Safety test question scapes, cuts, etc. sustained on-site must be treated and reported immidiately MSDS MSDS should be included for all chemicals onsite Note Taking Notes taken from the inspection reflect the conditions observed on site. • Be specific...facts not opinions • Identify proper personnel • Avoid vague terminology • Record critical data Pictures record area of site, direction, georeference photos • Use video to capture motion * May be used as evidence in legal proceedings Good Reporting Practices Complete and factual records • Support potential enforcement action • Communicate with others • Document what you see, do not speculate or assume • Report what you observe on that day (snapshot in time) • Make objective observations only...not subjective • Do not make personal observations about people • Provide copy of findings to appropriate parties Conclusions of reports • Use simple, short, direct sentences • Record accurate and specific details when possible • Consult key individuals if unsure of observations Corrective Actions in report Site Review: Review the Plan • Ensure the perimeter of the site is protected where applicable • Focus on discharge locations • Investigate entrances and exits • Make certain associated BMPs are in place and maintained, and bypass is not occurring • Ensure the Plan includes each phase of construction and the construction schedule is realistic based on site conditions Site Review: Industrial • Verify that onsite drainage systems match approved plans • Inspect for spills or illicit discharges • Storage and delivery areas • Inspect for proper containment and/or cover • Processes associated with construction activities that may contribute pollutants • Sampling Requirements site review post construction/MS4 -Review all archived files for information such as as-built or GPS records of drainage systems (especially for IDDE inspections) • IDDE - Illicit Discharge Detection Elimination Inspections • Familiarize yourself with SWMP (SWAMP) • Verify Inspection frequency The Inspection Process • Where is the SWPPP? • Review it • Are there any maintenance reports? • Review them • Have there been any problems or changes to the SWPPP or BMPs that have been repaired or replaced? • Do not let the site personnel dictate where you inspect (except if for safety reasons). The inspection report inspection freq rainfall data (past 24hrs) Weather and soil conditions at the time of inspection Project name and the project location the specific site area, type construction activity All relevant BMPs and their operating condition at the time of the inspection • Identify compliance issues and location of BMPs Evidence of previous or ongoing discharges Corrective Action report • Specify a time in which corrective actions are to be completed (determined by the permit language) Signature and Date Photographs or analytical reports • May be used to aid in documentation of site conditions inspection timeliness preform inspections per regulatory requirements (determined by the permit and detailed in the SWPPP) • Periodically, evaluate your inspection process. Conducting an audit of your process is a good practice. • Consider viewing your site from a different perspective Inspection issues -pollutant or Sediment leaving site - document, esitmate volume, pictures, sample -Water quality violation - sample, document all methods/equipment used to sample, pictures BMP maintenance or incorrectly installed - document all pics and damage, determine when/what action is req'd - plan revision req'd - identify need, document problem in report, request plan revision by preparer top 10 compliance issues 1. Too much soil exposed at one time 2. Missing and/or misunderstood sediment controls 3. Poor management of temporary stockpiles 4. Inadequate BMP maintenance 5. No BMPs to minimize vehicle tracking onto the road 6. Improper solid or hazardous waste management 7. Dewatering and other pollutant discharges 8. Poorly managed washouts (concrete, paint, stucco) 9. Inadequate self inspections 10.
