Creating an Effects Analysis
NOTE: NOAA Fisheries Greater Atlantic Regional Fisheries Office (GARFO) developed this spreadsheet as an in-house tool for assessing the potential effects to ESA-listed fish and sea turtles exposed to elevated levels of underwater sound produced during pile driving in riverine and inshore environments (coastal areas, bays, and rivers). For cetacean physiological (injury) effects, please refer to NOAA Fisheries' 2018 Marine Mammal Acoustic Technical Guidance document and user spreadsheet for assessing whether or not a project creates underwater noise that exceeds the permanent threshold shift (PTS) or temporary threshold shift (TTS) limits for listed cetaceans. NOAA Fisheries assumes no responsibility for interpretation and application of the results of these models by non-NOAA Fisheries users, as conditions at each project site may vary.

Writing Resources for Action Agencies
We encourage action agencies to utilize these writing resources while preparing their letter of concurrence requests.
Successful Examples of Incoming Consultation Letters
Looking for additional guidance to construct your Biological Assessment? Check out these FWS resources (e.g., Interagency Cooperation for Endangered Species course)! Note: there are subtle differences in the way NOAA Fisheries and FWS approach ESA Section 7 Consultation (E.g., ESA-listed species and critical habitat under NOAA Fisheries jurisdiction are NOT included in iPaC (GARFO has the Section 7 Mapper)).

For additional help, we strongly encourage action agency staff or non-federal representatives who may need to do ESA consultations to contact us. Please send questions, consultation initiation and concurrence requests to:
We are happy to provide the action agencies with technical assistance and guidance—before you begin the official ESA consultation process—to make the process easier, quicker, and more efficient.
