Objectives/Takeways
■ Industrial Stormwater Introduction
■ Stormwater requirements■ Potential pollutant sources■ New England framework
– MSGP Data Review
Acronyms
■ BMP – Best Management Practice■ ICP – Integrated Contingency Plan■ LID – Low Impact Development■ MSGP – Multi-Sector General Permit■ NOI – Notice of Intent■ NOE – No Exposure Certification■ NOT – Notice of Termination■ NPDES – National Pollutant Discharge Elimination System■ SPCC – Spill Prevention Controls & Countermeasures■ SWMP – Storm Water Management Plan■ SWPPP (SWP3) – Storm Water Pollution Prevention Plan■ TMDL – Total Daily Maximum Load
Regulatory Background
■ Point Source Pollution– Water Quality Act of 1965 – Federal Water Pollution Control Act Amendments of 1972– Clean Water Act of 1977
■ Non-Point Source Pollution– Water Quality Act of 1987 – Phase 1 (1990)
» Medium and Large MS4s » Industrial Stormwater Dischargers» Construction Sites of 5+ acres
– Phase II (1999)» Small MS4s» Construction Sites of 1+ acres
Regulatory Background
■ Industrial Stormwater Dischargers
– 1995 Multi-Sector General Permit– 2000 Multi-Sector General Permit
» Renewed– 2008 Multi-Sector General Permit
» Renewed three years after expiration– 2015 Multi-Sector General Permit
» Renewed two years after expiration
Storm Water Discharges – What do these states have in common?
Delegated States
■ Most states are delegated to oversee program– 46 are delegated
– States issue permits
■ Four states are not delegated– Massachusetts
– New Hampshire
– Idaho
– New Mexico
– EPA issues permits
New England States
State General Permit - Effective Date
General Permit - Expiration Date Comment
Massachusetts June 4, 2015 June 4, 2020 Federal Permit
New Hampshire June 4, 2015 June 4, 2020 Federal Permit
Maine April 26, 2011 April 25, 2016(September 2016 Draft) State Permit
Connecticut October 1, 2011 September 30, 2018(Extended from 2016) State Permit
Rhode Island August 15, 2013 August 14, 2018 State Permit
Vermont August 4, 2011 August 4, 2016(Administratively continued) State Permit
NPDES - Industrial
■ Permitting Options? – Multi-Sector General Permit (MSGP)
– Federal or state
– Meant to be easy
– No Exposure Certification (NOE)
– Still need to file!
– Individual Wastewater Discharge Permit
– Don’t want these for stormwater
Sectors & SIC
■ What is an SIC code? – “A Standard Industrial Classification code or SIC code is a four-
digit code describing the activities taking place at a facility. Facilities conducting multiple operations may have multiple SIC codes, one describing each activity.”
■ What is a Primary SIC code? – A primary SIC code describes the activity that generates the
highest net revenue at a facility.
Multi-Sector General Permit (MSGP) Applicability
■ Sectors organized by SIC Codes– Sector A: Timber Products
– Sector E: Glass, Clay, Cement, Concrete and Gypsum Products
– Sector M: Automobile Salvage Yards
– Sector L: Landfills (Active & Closed)
– Sector N: Scrap and Waste Recycling
– Sector P: Land Transportation and Warehousing
– Sector S: Airports
– Sector T: Wastewater Treatment Plants (>1 MGD)
Stormwater Changes
■ 2015 MSGP– Added NAICS code cross-reference
– North American Industrial Classification System
– Added specificity for effluent limits– Electronic filing required– Improved public accessibility
» Post plan» Provide plan elements in NOI
General
■ No Exposure Certification (NOE)– Activities are designed to prevent exposure to rain, snow, snowmelt
and/or runoff
– Material handling equipment or activities
– Material handling activities
» Storage, loading and unloading, transportation, or conveyance
– raw material, intermediate product, final product or waste product
» Final products intended for outdoor use are not required to be stored indoors or in a storm-resistant shelter.
Multi-Sector General Permit (MSGP) Implementation
■ SWPPP Contents■ Discharges to Water Quality Impaired Waters■ Endangered Species & Historic Places Evaluation■ Quarterly Visual Inspections■ Annual Reporting■ Benchmark/Numeric Effluent Monitoring■ Electronic Reporting To EPA
– Sample Results (<30 days)
– Inspection Reports (<45 days)
■ Employee Annual Training
