A mitigation plan is typically required with the permit application, including, as applicable, a plan to compensate for the impact to regulated waters as a result of the project. Id. at 2.
The Mitigation Guidance was meant to provide a standardized system for evaluating functional compensation offsets associated with proposed aquatic resource impacts, determining compensatory mitigation requirements, assisting in identifying measures to minimize proposed project impacts, reducing subsequent compensation requirements, and evaluating compensation proposals. Id. Prior to the Mitigation Guidance, Pennsylvania’s method for determining compensation for losses to aquatic resources was based on acreage and linear feet.
Due to pushback from affected entities, including mitigation banks and permittees, PADEP formed a stakeholder working group to review the Mitigation Guidance. PADEP officially rescinded the Mitigation Guidance “to reevaluate its effectiveness and review potential revisions through stakeholder outreach.” 53 Pa. …
