Engineering Plan Review (Letter of non-objection)

According to 18 AAC 72.600, engineering plans should be submitted to DEC for review and approval. To obtain a "letter of non-objection" an applicant must submit a copy the Permanent Storm Water Management Control Plan Review Checklist with all documents listed on the General Project Information page. See the Frequently Asked Questions for answers to the commonly asked questions.
