 NPDES Small MS4
Storm Water Program
           What is an MS4?
A municipal separate storm sewer system
(MS4) is:
A conveyance or system of conveyances... owned
by a State, city, town, or other public entity that
discharges to waters of the U.S. and is:
•   designed or used for collecting or conveying storm
    water
•   not a combined sewer
•   not part of a Publicly Owned Treatment Works
    (POTW)
      Phase I MS4 Coverage
Phase I covers Large and Medium MS4s

  •   Large MS4s are in places with a population of
      >250,000

  •   Medium MS4s are in places with a population
      of 100,000 < 249,999

  •   Many MS4s in places less than 100,000 have
      also been designated by the PA
   Phase II MS4 Coverage
A small MS4 is:

 Any MS4 that is not already
 designated and regulated as a
 medium or large MS4 under
 Phase I. This includes Federally-
 operated systems.
      Phase II MS4 Coverage
A Phase II-regulated small MS4 is any
small MS4:

•   Located in an “urbanized area”
    (nationwide designation) and not waived by
    the PA; or

•   Designated by the PA
   Urbanized Area Definition

A central place (or places) and the
adjacent densely settled surrounding
territory that together have a minimum
residential population of 50,000 people
and a minimum average density of
1,000 people/square mile.
Urbanized Area Map
 Determining Location in a UA
 Operators  of small MS4s should determine
 if they are located within the boundaries of
 a Bureau of the Census-defined
 “urbanized area” based on the latest
 decennial Census

 Operatorshave several options for finding
 the necessary information regarding UA
 boundaries
    Determining Location in a UA

   Appendix 6 to the preamble

   http://factfinder.census.gov/java_prod/dads.ui.
    homePage.HomePage
   State Data Centers
    Designation by the PA
The PA must develop and apply
designation criteria to all small MS4s
located outside of a UA that serve a
jurisdiction with a population of at
least 10,000 and a population density
of at least 1,000 people/sq. mi.
      Designation by the PA
         Designation Criteria
 Discharge   to sensitive waters
 High growth or growth potential
 High population density
 Contiguity to an urbanized area
 Significant contributor of pollutants to
  waters of the U.S.
 Ineffective protection of water quality by
  other programs
   Designation by the PA

The PA must also designate any small
MS4 that is contributing substantially to
the pollutant loadings of a physically
interconnected MS4 that is regulated
under the NPDES Storm Water
Program
    Small MS4 Waiver Option 1
Available for small MS4s in UAs where…

•   The small MS4 serves a population <1,000 within
    the UA

•   The small MS4 is not contributing pollutants to a
    physically interconnected regulated MS4

•   If the small MS4 is discharging to an impaired water
    body, storm water controls are not needed based on
    a TMDL that addresses the pollutants of concern
    Small MS4 Waiver Option 2
Available for small MS4s in UAs where…
•   The small MS4 serves a population <10,000
•   The PA has evaluated all waters that receive a
    discharge from the small MS4
•   The PA has determined that storm water controls
    are not needed based on a TMDL or equivalent
    analysis that addresses the pollutants of concern
•   The PA has determined that future discharges will
    not impact water quality.
Regulated Small MS4 Phase-In

 The PA may phase-in the
 requirements for regulated small
 MS4s with populations less than
 10,000 on a schedule consistent
 with a State watershed permitting

Interaction of the MS4,
   Construction, and
  Industrial Programs
Training Review

 We have addressed:
    Who is covered
    Who is responsible for obtaining permit
     coverage
    What is required and when

 Now will address:
    Similar but different requirements
    Multiple responsibilities
Changes to Industrial Program
 ISTEA moratorium will      expire
 “Noexposure” exclusion expanded to all
 industrial categories
 All   industrial categories must either:
   Submit   No Exposure Certification
   Apply   for Permit Coverage
Construction Permits
 Specific  Requirements for small
  construction will be in GP
 Current CGP expires 2/2003
 Small CGP will be issued by 12/2002
 EPA’s next CGP will contain requirements
  for all construction activity
 Requirements may be different for small
  and large construction
Small MS4 Program
 Small MS4 program will have general
  permits & NOIs as application
 All MS4s required to meet MEP standard
 Small MS4s have no requirements for:
    Monitoring

    Oversight of Industrial Activity
Multiple Responsibilities
Construction Operators

 Any location - must obtain NPDES coverage
 Located in regulated small MS4 - must also comply
  with MS4’s construction requirements
 MS4 construction requirements similar to CGP but no
  SWPPP required
 CGP can reference qualifying local program
 Compliance with QLP is compliance with NPDES
  permit
Reasons for MS4 Construction
Requirements

 Requirements tailored   to locality
 Local  oversight more effective than just
  State oversight
Reasons for NPDES Construction
Requirements

 SWPPP required
 Federal   and Citizen enforcement
 Controls discharges  from construction to
  all waters of US, not just to MS4s
 Multiple Responsibilities
 Municipal Operators

 Ifregulated small MS4 is construction or
  industrial operator it must obtain permit
  coverage for those activities
 Coverage  may be through 3 GPs or individual
  permit that includes industrial and municipal
  requirements
 Small MS4 application date is same for
  municipal and industrial requirements
Construction Phase I
 Compliance Issues
      The following is a Review of current
    Requirements and common problems
  for Phase I permits. Phase II construction
permits will use a similar type general permit.
This is best info that Enforcement can provide
     until the Phase II permits are issued.
     Construction Permitting
         needs a permit if the overall
 Facility
  common plan of development or sale is
  5 or more acres and not otherwise
  exempted
 Exemptions:
   Municipal projects if municipality is less
    than 100,000
   Agricultural
             Who Needs Permitted
   EPA Permits the “Operator”:
       The "operator" is the party or parties that either
        individually or taken together meet the following
        two criteria:
            1) They have operational control over the site
             specifications (including the ability to make modifications
             in specifications); and
            2) they have the day-to-day operational control of those
             activities at the site necessary to ensure compliance with
             plan requirements and permit conditions (e.g., are
             authorized to carry out activities identified in the plan).
                  Operator
 Typical   Commercial Construction Site
   Developer (controls site specs)
   General Contractor (day-to-day activities)

 Typical   Residential Construction Site

 General Contractor will usually have to add
  this to the SWPPP because the engineer will
  not know prior to construction where or if the
  general contractor will make use of these
  facilities.
            NPDES Inspections
   Can be performed by EPA, TNRCC, or the
    MS4 City.
       Failure to allow your MS4 city to inspect your
        facility is a federal violation of the NPDES
        construction general permit.
 EPA authorized to Inspect and gather
  information by Section 308 of the CWA.
 EPA Policy that if any facility denies entry for
  an NPDES inspection, that EPA will obtain a
  warrant.
                   Enforcement

        before a RJO or ALJ
Region 6 Enforcement Actions
   Most first time violators are receiving
    administrative penalties of $15,000-50,000
    assuming no significant environmental
    impacts.
       Each Penalty is determined on a case-by-case
        evaluation in accordance with the Clean Water Act
        Settlement Policy of 1995.
   Wal-mart and General Contractors
       Recently settled for $1,000,000 for violations at 17
        facilities plus implementation of an environmental
        management plan.
                   Citizen Suits
 Authorized by Section 505 of the Act for up to
  $27,500 per day per violation
 Can enforce Civil violations only
 Can only be for ongoing violations and EPA
  must be given 60 days notice of a suit
 EPA’s diligent investigation and prosecution
  takes precedence over citizen suits
 Penalty monies are paid to US Treasury and
  not the plaintiffs
       Judges frequently award successful plaintiffs
        money to cover court costs
                           Its Just Dirt
   Why do we regulate the discharge of dirt?
       It’s the 2nd most frequent parameter listed as
        reason for impairment of water bodies as reported
        in the 305(b) reports to Congress.
       Discharge of Sediment and Erosion from
        Construction have environmental impacts
            High Turbidity and TSS
            Lowers Dissolved Oxygen
            Acts as a carrier for more toxic pollutants such as metals
            Fills up bottom of lakes/streams
                  May result in need for lakes to be dredged like at White
                   Rock Lake in Dallas to the tune of $18,000,000
                  Inhibits reproduction of aquatic species that are inhibited
                   by large sediment loads (e.g. salmon that need rocks on
                   bottom of stream to lay eggs)
            Pollution Prevention
   P2 is fairly new to EPA
       Works on the theory that preventing pollution from
        getting in the discharge is as effective as removing
        in through treatment
 EPA encouraging P2 to work as a cost
  effective method of protecting the
  environment.
 What if P2 as a whole for the construction
  industry doesn’t work?
       May have to go to Treatment (e.g. package plants
        for treatment of storm water)
       Much more expensive
