Chairman and Members of the West Orange Township Planning Board August 15, 2025 Re: West Essex Highlands, LLC (PB 24-01) Our File No. 115.WRP0179.V01 Response To Objector’s Stormwater Management System Review Page 9 Further, Special Condition #2 of the NJDEP Permit referenced above indicates that the Department has determined that this project meets the requirements of the Stormwater Management Rules at N.J.A.C. 7:8. 2.7 Separation of Sanitary Infrastructure and BMP “The design has a sanitary pipe traveling through porous pavement system (Figure 11). While Princeton Hydro could not find a specific rule against a sanitary line traveling through a subsurface basin, there are rules dictating adequate separation between stormwater piping and sanitary piping.” Sanitary sewer piping will not be installed within any stormwater management system. The Applicant’s Engineer will be required to revise the plans to indicate the same prior to any construction. 3.0 Summary: Informational/Opinion. No comment needed.
