Draft Compensatory Mitigation Eligibility and Accounting Determination Form

STEP 1. ELIGIBILITY

INSTRUCTIONS: This eligibility worksheet is used to determine whether a proposed compensatory mitigation site is ecologically appropriate to offset proposed impacts. Final eligibility is determined
by the agency. The expectation is that compensatory mitigation sites provide an ecological match (i.e. class, function, and value) to the impact site. In some circumstances, an exception to ecological match
may be allowed if the permittee demonstrates that the proposed compensatory mitigation site addresses local or watershed needs or priorities. Enter data in boxes in cyan colored cells only. Boxes in yellow
colored cells will populate automatically as related control buttons are selected.

Criteria Response Result Comments
Expectations for providing ecological match for wetland impacts Does the mitigation site replace all of the following: Aquatic Resources of Special Concern must be replaced in-kind and may not otherwise meet all other criteria.
a) HGM class(es) and sub class(es)? * Select Yes or No from drop-down list.
b) Cowardin system(s) and class(es)? * Select Yes or No from drop-down list.
c) Group-level functions and values? * Compare OWRAP ratings between the impact site and the mitigation site (predicted scores) to determine this. Select Yes or No from drop-down list. This criterion does not apply when purchasing legacy credits, ILF credits not associated with a DSL approved project, or PIL. Does not apply to non-tidal wetland impacts less or equal to 0.2-acres purchasing credits.
Expectations for providing ecological match for stream impactsDoes the mitigation site replace all of the following: Aquatic Resources of Special Concern must be replaced in-kind and may not otherwise meet all criteria.
a) Flow permanance (intermittent or perennial)? * Select Yes or No from drop-down list.
b) Stream size class (small, medium, or large)? * Select Yes or No from drop-down list. Stream size class as set forth by Oregon Department of Forestry in OAR 629-635-0200 Sections (13) and (14). Mitigation Planning Map
c) Essential Indigenous Anadromous Salmonid Habitat (ESH) designation, if the impact is to an ESH stream? Select Yes, No, or Impact site is not ESH from the drop-down list.
d) Group-level functions and values? * Compare SFAM ratings between the impact site and the mitigation site (predicted scores) to determine this. Select Yes or No from the drop-down list. This Criterion does not apply when purchasing legacy credits, ILF credits not associated with a DSL approved project or PIL.
If any criterion above are not met, determine whether the mitigation site might qualify for an exception (as a watershed priority) by answering the following two questions. If all criteria above are met, skip the next two questions and move to Step 2: Accounting Aquatic Resources of Special Concern are not eligible for an exception and must be replaced in-kind.
Possible Exception to Ecological MatchDoes the mitigation site:
a) Address a watershed priority, as identified in a planning or assessment document, report, or other data? * Must be fully described in the permit application. Select Yes or No from the drop-down list.
b) Provide a high level of the functions and values that are relevant to the targeted priority (either currently or post-construction)? * Must be fully described in the permit application. Select Yes or No from the drop-down list.
