Mott MacDonald Zayibeth Carballo, PE.-LS, CME, CFM, Assistant Municipal Engineer July 26, 2022 Page 7 of 10 tool will be such that it can be used using NJDEP’s example templates and then linked to the Township GIS system. For this task, we assume 18 hours of engineering and GIS specialist time but limit our scope to the assistance in developing the tool to be used by West Orange. 2.7 Item 16 Total Maximum Daily Load (TMDL)/Impaired Waterway - Part IV.C.2 The NJDEP Audit letter requires West Orange to identify TMDL’s for the streams that fall within the municipal borders to assess initially and then annually stormwater related pollutants to prioritize maintenance schedules and repairs as well as overall strategies to address the sources of pollutants of the published TMDL’s. Strategies that the Township implements shall be incorporated in the SPPP as Optional Measures. Given the above, Mott MacDonald proposes to review the published TMDL’s which based upon our initial review involve seven (7) TMDL’s for streams and one (1) for lakes (Verona Park Lake). The TMDL’s for the streams include Fecal Coliform and Phosphorus. The TMDL for Verona Park Lake is for Phosphorus. Given the current permit requirements, Mott MacDonald’s services are limited to documenting a formal review of the TMDL’s noted above and preparing recommendations related to maintenance priority with the results written into the SPPP and updated Municipal Stormwater Management Plan. For this task, we assume 36 hours of engineering and scientist time but limit our scope to the minimal requirements in the current permit. Again, be advised that similar to Item 11, the new permit cycle will significant requirements to this aspect of the permit that would become effective in 2023. Mott MacDonald could provide a separate proposal to commence with services to address the permit requirements that will be in place by 2023. 3 Deliverables For the above scope, our deliverables will include: ● Updated Outfall Map ● Updated Municipal Stormwater Management Plan ● Copies of all inspection reports (inspection tool, data and pdf report) ● GIS geodatabase containing the updated inlet and outfall data. ● Deliverables noted in the September 9, 2022 Proposal letter for Item 11b We will submit 2 paper copies of the deliverables along with a readable electronic version of all documents. 4 Proposed Fee We propose our fee
