What is stormwater or “runoff”?
Stormwater runoff is the excess water that “runs
infiltration and evapotranspiration has occurred
Factors Impacting Runoff
Factors:
The Virginian Pilot December 5, 2010
Examples of Pollutant Sources Associated with Stormwater Discharges
fertilizers
boats
products
Pollution Hydraulic modifications Ecological impacts Property / infrastructure damage Fines and lawsuits Relationship with the public
Pollutants Associated with Runoff
Sediment Soil particles transported from their source Biochemical Oxygen Demand (BOD)
Toxics
Debris Litter and illegal dumping Nutrients
dissolved and suspended in water (commonly found in fertilizer and plant material):
Bacteria/ Pathogens Originating from:
Thermal Stress Heated runoff, removal
vegetation
Silted up pond
Impacted channel
What is impervious cover?
Hardscapes and other surfaces that do not allow stormwater to infiltrate into the ground
Are residential lawns “impervious”?

Impervious Cover & Stream Quality
At 10% impervious cover, stream degradation (e.g., changes in the aquatic biological community) is detectable.
At 25-40% impervious cover, streams no longer support biological/human uses.

Phase II Regulations – Small MS4 General Permits (40 CFR 122.33-34)
If you are the operator of a “small MS4”, you are required to seek coverage under an individual or general NPDES permit
permit To be covered under a general permit:
program that is designed to reduce the discharge of pollutants from the MS4 “to the maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the CWA.”
permitting authority
implemented for each of the six minimum control measures, (2) the measurable goals that will be achieved for each of the BMPs (deadlines and interim milestones), and (3) the persons responsible for implementing the MS4’s stormwater management program
Focus of the ruling: Ninth Circuit found deficiencies in the Phase II stormwater regulations regarding the procedures to be used for providing coverage to small MS4s under general permits The court vacated the relevant portions of the Phase II regulations, and remanded to EPA to fix the deficiencies:
reduction in discharges would be the maximum practical reduction.”

public or subject to public hearings contravene the express requirements of the Clean Water Act.”
NRDC/EDC petition to Ninth Circuit (2014)
Petitioners asked the Ninth Circuit to require EPA to take action to address the 2003 EDC v. EPA ruling Petition requests the Court to order EPA to take the following actions:
statement that directs permitting authorities to comply with the 2003 EDC order pending further rulemaking. “This action is needed to ensure that state permitting agencies do not continue to mistakenly rely on the vacated rules.”
date) a rule revising the Phase II small MS4 regulations to address the “procedural deficiencies” found in the Court’s 2003 order.
Ninth Circuit has given EPA until June 12 to respond
Provided recommendations to permitting authorities for how to administer their general permits in light of the EDC v. EPA ruling Public Availability of NOIs:
public with sufficient time to allow for a meaningful public comment
days before authorization to discharge Opportunity for Public Hearing:
for requesting a public hearing on an NOI, the standard by which such requests will be judged, the procedures for conducting public hearing requests that are granted, and the procedures for permitting authority consideration of the information submitted at the hearing Permitting Authority Review of NOIs:
to ensure consistency with the permit
need to specify when authorization occurs (e.g., after notice from the permitting authority, or after the expiration of a waiting period)
MS4 Permit Improvement Guide (2010) Revisions to 2002 Memorandum on TMDLs and Stormwater Permits
permitting authorities establish clear, specific, and measurable permit requirements to implement the minimum control measures in MS4 permits
Some permitting authorities have modified their small MS4 general permit procedures
comments on individual NOIs and/or request a public hearing Some permitting authorities individually review NOIs and stormwater management programs Some permitting authorities have established more specific permit conditions for individual MS4s within the general permit – lessening the importance of the stormwater management program to establishing the substantive requirements Some permitting authorities have decided to individually permit their small MS4s
Scenario 1: Modify procedural requirements for general permits
Include requirements for permitting authority review, public notice of NOIs, and providing the
necessary) on individual NOIs/SWMPs Potential rule changes:
procedures
Issues:
result of permitting authority review and public notice/hearing comments
Scenario 2: Clarify permitting authority’s role in establishing permit requirements
Clarify that permitting authority is responsible for establishing permit requirements that meet the standard of reducing pollutant discharges to the “maximum extent practicable” and that it has addressed the six minimum measures and other relevant requirements Potential rule changes:
general permit is where the enforceable requirements are established
Issues:
streamlined or cut? How does this affect the permit authority review and public participation issues in the remand?
