Title: Overview of RIPDES Construction General Permit Requirements
1Overview of RIPDES Construction General Permit
Requirements
Developed by Greg Goblick, Laura
Stephenson RI Department of Environmental
Management RIPDES Permitting Program
2Introduction RIPDES Construction Storm Water
Program
- Review and introduction of Phase I and
- Phase II requirements
- When is a permit required?
- Who is responsible to implement the permit?
- Who is responsible for compliance?
3Goals of the Construction Storm Water Program
- Minimize erosion during construction
- Reduce/eliminate pollutants in storm water to
protect water quality - Consider post-construction storm water management
4Large Construction (Phase I) Permitting
- Construction General Permit (CGP)
- RIPDES issued in 1993
- Re-issued March 1998
- Re-issued September 9, 2003 (Phase II
requirements incorporated in new CGP) - Authorization under the old CGP
- Allowed automatic authorization for projects
approved by CRMC, DEM Freshwater Wetlands, DEM
WQC (only an NOI needed to be submitted to
RIPDES)
5Small Construction Permitting (Phase II)
- Municipalities required to developed local
programs (refer to Small MS4 General Permit) - Covers construction activity one or more acres
- RIDEM permits required Statewide
- No waivers
- RIDEM organized 3 focus group meetings
(consultants, municipalities, environmental
organizations, state and federal agencies to
discuss draft CGP permit)
6SWPPP Requirements
- 1. Stamped/signed by one of the following
- Registered Professional Engineer (P.E.)
- Certified Professional in Soil Erosion Control
(CPESC) - Certified Professional in Storm Water Quality
(CPSWQ) - Registered Landscape Architect
- Note SWPPPs that require engineering must be
stamped/signed by P.E.
7SWPPP Requirements cont.
2. Identify potential sources of pollutants which
may reasonably be expected to affect the quality
of storm water discharges associated with the
construction activity.
8SWPPP Requirements cont.
-
- 3. Describe and ensure the implementation of
Best Management Practices (BMPs) used to reduce
or eliminate pollutants in storm water
discharge(s) and assure compliance with the
permit.
9SWPPP Requirements cont.
- 4. BMP selection shall include an evaluation of
the effectiveness of available practices and be
made with proper references.
10Permit Changes Qualifying Local Programs (QLPs)
- Permit includes conditions that incorporate
department approved QLPs -
- Compliance with QLP compliance
- with RIPDES
- QLPs issue permits for sites 1-5 acres and
greater than 5 if QLP chooses to do so
11Permit Changes Reasons for QLPs
- Requirements tailored to locality
- Local oversight more effective than just State
oversight - Protect local infrastructure and prevent
introduction of pollutants into the local storm
sewers and drainage system (MS4) - Streamline duplicative permitting requirements
- Reduce permit fees
12Permit Changes Phase II Requirements
- Requires permit coverage for
- Construction activity disturbing gt 1 acre and lt
5 acres - Construction activity below 1 acre that is part
of a larger common plan of development or sale - Potential permit coverage for
- Construction activity that disturbs less than 1
acre of land may be designated based on water
quality impact
13Permit Changes Streamlining
- Incorporate RIPDES NOI requirements in wetlands
application process - Wetlands application serves as RIPDES NOI for all
sites greater than 1 acre - NOI does not have to be submitted for sites with
a Qualifying State or Local Program permit or
approval - Less paper, less time, less money!
- Federal/State agencies do not have to apply
for QLP approval if a RIPDES Permit is obtained
14Permit Changes NOI Form Part IXNatural
Heritage Areas
- Professional (a P.E., CPESC, CPSWQ, or Registered
Landscape Architect) must certify information in
Part V of NOI - Is the site within or directly discharging to a
Natural Heritage Area? (Yes or No) - If the site is within or directly discharging to
a NHA, do you have previous approval from the DEM
Natural Heritage Program (NHP)? If yes, include a
copy of the approval letter
15Permit Changes Part IX NHAs Continued
Projects that propose a storm water or allowable
non-storm water discharge to or has discharge
related activities that may potentially affect a
NHA
- Submit Map
- Location of construction
- Street address
- Nearest utility pole number
- Assessors plot and lot
- Total area of site
- Limits of disturbance
16Permit Changes NOI Form Part X SWPPP
Development
- Needs to be filled out for activities that are
not required to submit a SWPPP (see
authorization) - Ensure that a site specific SWPPP was prepared
consistent with requirements - Does not alleviate or limit liability and sole
responsibility of the owner/operator to implement
amend SWPPP
17Authorization
- Do I require any of the following?
- CRMC permit
- QLP approval
- WQ Certification
- Wetlands permit
If CRMC or QLP Approval, and WQ Cert (if appl.)
YES
THEN
YES
NO
Is my site gt 5 acres?
Is my site 1 lt x lt 5 acres?
If Freshwater Wetlands Permit
YES
YES THEN
THEN
Submit NOI and approval
Automatically Authorized
18Authorization
Is my site 1 lt x lt 5 acres?
- Do I require any of the following?
- CRMC permit
- QLP approval
- WQ Certification
- Wetlands permit
NO
NO
Is my site gt 5 acres?
YES
YES
Submit SWPPP and NOI
Discharging directly to a NHA?
YES
NO
THEN
Prior approval from NHP?
Submit NOI
THEN
Authorization upon notification
NO
Automatic authorization w/i 30 days
YES
Submit NOI
Submit NOI approval
Automatically authorized
THEN
19Future ImprovementsKick it up a notch
Termination of project - P.E. certifies that
any permanent structures constructed are
according to SWPPP/design manual Revise goals
to be consistent with updated Storm Water Design
Manual
20Future Improvements cont.
Consider additional measures for final
stabilization and long term storm water
management Consider requiring various measures
such as sediment traps, basins or other controls
based on area of disturbance
