I advised that this would require a site visit by MRO to confirm, if they are asking for agreement of changes before we enter them into our BIMS system. I'm also copying our General Permits coordinator, Brittany Cook.

Ms. Georgoulias, Hanley Environmental was contracted by Metro Stone & Granite to assist with stormwater compliance in advance of the new general permit to be issued June 1, 2023. We are submitting this request to update the number of outfalls at the facility from 3 to 1. The facility previously identified three outfalls in its application in 2022. During a site visit on April 21, 2023, Hanley Environmental identified that site stormwater from industrial areas flows to an unnamed roadside intermittent stream (as classified by USGS). The unnamed intermittent stream flows west until discharge into East Fork Twelvemile Creek. Therefore, I am submitting this request to reduce the number of outfalls. Facility information and a description of site drainage is discussed below, and two site maps are attached for reference. Facility Name: Metro Stone & Granite, Inc. Monroe Facility Location: 1720 Tower Industrial Drive Monroe, Union County, North Carolina 28110 NPDES ID: NCG070000 Certificate of Coverage No. NCG070227 Site Coordinates (center): Latitude: 35.03194 N Longitude: 80.62784 W (Obtained from Google Earth) Receiving Water: East Fork Twelvemile Creek Site maps for this facility are included as Figures 2 and 3. The site maps show the locations of the site buildings, site topography, approximate stormwater flow directions, material storage areas, drainage structures, the outfall drainage area, parking lot, and other impervious areas. Generally, runoff in the northern, eastern and western portions of the site is controlled by surface topography and drains as sheet flow to the intermittent stream along impervious and pervious surfaces. Runoff on the southern portion of the site drains across impervious surfaces to stormwater inlets, then flows through underground piping and a discharge culvert, and into a vegetated swale before ultimately flowing into the intermittent stream. Drainage features ultimately discharge to a stormwater outfall, identified as Outfall 001, which is the location where the intermittent stream leaves the property boundary. Additionally, a portion of stormwater runoff is expected to infiltrate pervious surfaces at the site, or travel as sheet flow from areas outside the developed industrial portion of the site toward low-lying areas. The outfall and stormwater features are presented on Figure 3. The outfall location (including latitude/longitude), acreage, and percentage of impervious area is summarized below. Outfall Location Latitude Longitude Approx. Approx. Percentage of Number Total Impervious Impervious Area Area (Acres) Area (Acres) Outfall 001 Northwestern 35.032105 -80.628312 0.91 0.65 71.67% Corner of Property Outfall 001 discharges from the property boundary and continues to flow west towards East Fork Twelvemile Creek. We are requesting your concurrence to recognize a single outfall at this facility. Please contact me if you have any questions or would like to discuss this request.
