Proposal for Professional Engineering and Permit Assistance Services Municipal Stormwater Management Plan Updates Permit Compliance for NJPDES: NJG0151190 / PI ID#: 168118 West Orange Township, Essex County, New Jersey July 26, 2022, revised September 9, 2022 Dear Ms. Carballo: Thank you for reaching out to Mott MacDonald related to updating several items related to the West Orange Township Municipal Stormwater Management Plan, Stormwater Pollution Prevention plan and Municipal Separate Stormwater Sewer System (MS4 permit) updates and compliance. As discussed, these updates are of priority due to the letter received by NJDEP on December 4, 2020 which captures the Stormwater Compliance Assistance Audit (Audit Letter) findings from the NJDEP that was conducted on July 31, 2019. The Audit Letter covers 17 items to which the Township must provide response and have required action items documented. The Audit letter is attached to this letter as Attachment 1. We also note that on June 21, 2022 NJDEP’s Office of Water Compliance and Enforcement (Northern Regional Office) issued a second letter based upon an inspection conducted by the Department on February 17, 2022 related to issuance of a Notice of Violation (NOV) based upon non-compliance with a checklist of items that the inspector used during the evaluation that assess components of the MS4 permit and SPPP. At the time of the inspection, the NJDEP inspector cited submission of the Annual Report and Certification as out of compliance and therefore cause for the NOV. However, it is our understanding that the annual report was in the process of being submitted at the time. It is noted however, that there are several items that are under review and an overall comment by the inspector that the items noted in the 2020 Audit Letter. 1 Background The two primary documents requiring update are the Stormwater Pollution Prevention Plan (SPPP) and the Municipal Stormwater Management Plan (MSWMP). Both are a requirement of the Tier A MS4 Permit and both require updates. Based upon our conversation, the intent is to have West Orange be Zayibeth Carballo, PE.-LS, CME, CFM, Assistant Municipal Engineer 25 Lakeside Avenue West Orange.
