| DEP BMP GP 104 - The Latest with EPA, Upcoming Deadlines & What the Future Holds |
|
The DEP Bureau of Mining Program’s general permit GP-104 is a general permit, the use of which has to be approved by EPA. General permits are approved for five years use, at which time they need to be updated and resubmitted to EPA for approval. This version is set to expire on February 21, 2021. The Department submitted the proposed permit to EPA last year, and while they are working on it with EPA, EPA has yet to give final approval on it.
BMP GP 104 is a permit for those discharges that are composed entirely of stormwater.
If you currently have an authorization or permit with an expiration date after February 2021, once EPA approves this new version, you will get a notice that you have the option to certify the reissued permit or apply for an individual NPDES permit. If you choose the certification, your coverage expiration date will revert to the five-year date of this permit or 2026. There will be no permitting fee for this.
New or reapplications, including renewals, will be issued under the 2021 reissuance and will all have the same 2026 expiration date regardless of the actual date coverage goes into effect. The Department is already working on easy renewal process for coverage past 2026.
In this new permit version:
- there are restrictions for use in impaired watersheds,
- the effluent limits were changed to eliminate the 30-day average and daily maximum. All you will have is an instantaneous max limit.
- there are requirements to minimize exposure of processing and material storage areas to precipitation,
- there are updated standard conditions and definitions to be consistent with other and or current requirements.
