What is the timing for completion of the NADR and who should sign the document?
A. The purpose of the NADR is to gather both the engineering and acoustic information of all noise abatement considered into one document. The project engineer is responsible for developing and signing the document. Because acoustic information is included from the noise study, the Office Chief for the environmental branch should also sign the NADR. For consultant developed NADR’s, in addition to the other signatures the consultant Project Manager’s signature should be included. The NADR needs to be completed early enough for the information to be included in the Draft Environmental Document prior to public circulation.
