1. Streambank Stabilization Permitting and BMP Considerations Permitting Overview Watershed Considerations Best Management Practices Administratively Complete Package*

2. 404 / 105 Permitting Pennsylvania State Programmatic General Permit (PASPGP-3) Bureau of Dams & Waterways Management (BDWM) General Permits (GP) Departmental Encroachment Permit

3. PASPGP-3 Federal Clean Water Act, Section 404 Permit Allows single agency review and processing* Eliminates redundant reviews* Streamline permit review process Improves program efficiency Use for single and complete projects Impacts limited to: 250 feet of stream* = 1 acre wetlands * = 500 streambank stabilization w/ GP-3

4. Ineligible for PASPGP-3 Lake Erie – activities which require a JPA or EA GP-15 Impacts > 1 acre of wetland impacts Special instances of EPA authority

5. Permit Categories Category I Category II Category III

6. Category I Activities that qualify for Pennsylvania's General Permits GP-3 Streambank stabilization = 500 linear feet Gravel bar removal = 250 linear feet GP-7 Individual impacts to wetlands = .10 acres* Cumulative impacts to wetlands = .25 acres* Roadway stream crossings = 100 linear feet Cumulative stream impacts < 250 feet Emergency Permits Some PADEP waivers Waiver 1 – small dams Waiver 7 & 8 – field drainage Waiver 12 – testing devices Waiver 14 – pond maintenance

7. Category II Review & comment by Corps and other agencies Activities that do not qualify as a Category I and III GP-3 GP-7 Projects requiring publication in the PA Bulletin for public comments and review Individual Permit Dam Permit Environmental Assessment Some PADEP Waivers Waiver 11 – abandoned dam removal Waiver 16 – restoration activities

8. Category III Requires Separate Federal Review and Authorization Projects w/in LeBoeuf, French, Conneauttee Creeks and Conneaut Outlet Areas with impacts to species of special concern (threatened or endangered) General Permits GP-3 r/t gravel bar removal >250 linear feet Additions to previously authorized single and complete project which exceed cumulative impacts July 1, 2007 wetland impacts w/o conservation easement and / or deed restriction areas After the fact permits PADEP Waiver 2

9. PA General Permit GP-1 - Fish Habitat Enhancement Structures GP-2 – Docks & Launches* GP-3 – Streambank Stabilization/Gravel Bar* GP-4 – Intake / Outfall Structures** GP-5 – Utility-line Crossings* GP-6 – Agricultural Crossings* GP-7 – Minor Road Crossings* GP-8 – Temporary Road Crossings GP-9 – Agricultural Activities GP-11 – Maintenance, Rehab, Replacement GP-15 – Private Residential Wetland Construction*** Cannot be used in EV Watersheds* Cannot be used in HQ or EV Watersheds** Not eligible for SPGP-3 ***

10. HQ* / EV* Streams Hubble Run* Spring Creek* Lake Pleasant Outlet* Beaver Run* Trout Run* Crooked Creek* Godfrey Run* Thomas Run* Twelvemile Creek*

11. BDWM-GP-3 500 linear feet of impacts Streambank Gravel bar Maintenance required DOES NOT include: Channel realignment Wetland encroachments Construction of levees

12. Streambank Stabilization Grading Dumped rock grouting not authorized key trench recommended Walls cannot use tires 6 feet limit Rock weirs Diversions Log veins* J-hooks* *Limited to 25% stream width

13. Gravel Bar Limited to 6” above water elevation at the time of work. All material must be removed from floodway. Cannot be used to remove gravel bars with vegetation > 50% total surface area. Category III > 250 feet

14. Gravel Bar Limited to 6” above water elevation at the time of work. All material must be removed from floodway. NO bulldozers Cannot be used to remove gravel bars with vegetation > 50% total surface area. Category III > 250 feet

16. Gravel Bar Limited to 6” above water elevation at the time of work. All material must be removed from floodway. Cannot be used to remove gravel bars with vegetation > 50% total surface area. Category III > 250 feet

17. Gravel Bar Limited to 6” above water elevation at the time of work. All material must be removed from floodway. Cannot be used to remove gravel bars with vegetation > 50% total surface area. Category III > 250 feet

27. E&S Plan / BMPs Addressing baseflow of stream Immediate stabilization of disturbed area Addressing access to project area “Traditional” BMPs

28. Addressing Baseflow Low flow conditions Divert flow away from work area Cofferdams Sheet piling Convey flow past work area Temporary culvert Pumped by-pass Temporary by-pass channel Stone filter

29. Addressing Baseflow Low flow conditions Divert flow away from work area Cofferdams Sheet piling Convey flow past work area Temporary culvert Pumped by-pass Temporary by-pass channel Stone filter

30. Immediate stabilization Stabilize prior to re-diversion Erosion control fabric Bank protection Vegetative stabilization Seeding Cuttings & plantings

31. Access Excavations from Bank BDWM-GP-8? Bridge Culverts Clean stone No “fill material”, or streambed material Access Roads Waterbar Broad-based Dips Culverts

32. “Traditional” BMPs Silt-fence(?) staging areas access roads stockpile areas Hay/straw bales in channel – NO Stone filter Pumped filter bag Well vegetated Flat area Access?
