My intent is to have an open throat inlet (2 sides) with a concrete slab top located in a conveyance channel. The opening is proposed to be 1'x 4' and the invert of the opening set to equal the proposed max. volume water elevation. The opening will align with the channel and allow the excess flow to pass and exit the site. A channel is proposed around the pond with a release at the property corner. 8.

WILMINGTON DISTRICT FACILITY EXPANSION WILMINGTON, NORTH CACtOLINA PROJECT OWNERSHIP THE SITE OF THIS PROPOSED WORK IS OWNED BY WASTE INDUSTRIES, INC., 3949 BROWNING PLACE, RALEIGH, NC, A RALEIGH BASED SOLID WASTE MANAGEMENT COMPANY. THE EXISTING FACILITY IS A DISTRICT FACILITY HOUSING THE ADMINISTRATIVE OFFICES, COLLECTION VEHICLE AND CONTAINER MAINTENANCE AND LIMITED RECYCLING FUNCTIONS. PROJECT DESCRIPTION THE PROPOSED WORK SHALL INCLUDE THE SITE EXPANSION OF AN INDUSTRIAL FACILITY TO ACCOMODATE THE ADDITIONAL STRUCTURES AND THE REQUIRED PARKING AREAS. AT PRESENT, THE FACILITY HOUSES THE DISTRICT COLLECTION OPERATIONS AND ADMINISTRATIVE OFFICES. THE PROPOSED EXPANSION WILL CREATE A SOLID WASTE MANAGEMENT FACILITY TO INCLUDE THE ADDITIONAL FUNCTIONS OF RECYCLING AND CARDBOARD PROCESSING. THE FINAL COMPLEX IS VIEWED AS A COMPREHENSIVE WASTE MANAGEMENT FACILITY INTENDED TO REDUCE THE WASTE STREAM AS MANDATED BY REGULATIONS. SITE DESCRIPTION THE WASTE INDUSTRIES, INC. WILMINGTON DISTRICT FACILITY IS LOCATED ON THE NORTHEAST SIDE OF HIGHWAY 421 NORTH, APPROXIMATELY 3 MILES FROM WILMINGTON, NC. THE SITE IS 6.428 ACRES WITH APPROXIMATELY 4.5 ACRES DEVELOPED. THE UNDEVELOPED SECTIONS IS LOCATED ADJACENT TO HWY 421 AND IS CHARACTERIZED AS A KNOLL COVERED WITH PINE VEGETATION. THE SITE'S SOIL CI'.ARACTERISTICS ARE SILTY SANDS AND CLEAN FREE-DRA,'NAING SANDS. THE ESTABLISHED INFILTRATION RATES RANGE FROM 22 TO 110 GALLONS PER HOUR PER SQUARE FOOT. THE SITE'S LANDSCAPE POSITION IS CONSIDERED "RIDGE TOP" WITH POSITIVE OFF -SITE DRAINAGE AND NO ON -SITE DRAINAGE FROM ADJACENT AREAS. STORMWATE04ANAGEMENT A STORMWATER PERMIT IS REQUIRED FOR THIS PROJECT FROM THE NORTH CAROLINA DEPARTMENT OF ENVIRONMENTAL HEALTH AND NATURAL RESOURCES. THE SITE IS CONSIDERED HIGH DENSITY WITH AN INFILTRATION SYSTEM DESIGNED TO CONTOL RUNOFF VOLUME CREATED BY A ONE INCH RAINFALL FROM THE IMPERVIOUS SURFACES. GIVEN DATA C VALUES PAVEMENT/GRAVEL 0.95 GRASS/LANDSCAPE 0.30 i VALUES a 3.90 i10 5.50 NARRATIVE PAGE 2 PROCESS CULVERTS: THE CULVERTS WERE SIZED FOR THE Q10 FLOW. THE OUTLET PROTECTION WAS BASED ON Q10, V10 AND SIZED ACCORDING TO THE NYDOT CHART AND THE, NRCD PROGRAM. TH`E V10 AND DEPTH OF FLOW WERE DETERMINED BY THE NRCD PROGRAM MODEL AND THE STONE SIZE CHECKED VIA TRACTIVE FORCE. DITCHES: THE DITCHES WERE CHECKED BY MANNINGS AT Q10 WITH A GRASSED LINING (n=0.03) AND A MAX. ALLOWABLE VELOCITY OF V=4.0 fps. ALL DITCH SECTIONS WITH A V10 > 4.0 fps WERE DETERMINED TO REQUIRE ARMOR AS A PERMANENT LINING. NO DITCH SECTION RELATED TO THIS PROJECT WERE COMPUTED TO REQUIRE ARMOR. EACH GRASSED LINED CHANNEL WAS TESTED FOR A TEMPORARY LINING AT Q2, V2 WITH A MAX. ALLOWABLE VELOCITY OF 2.5 fps. IF NEEDED, THE CHANNELS WERE TESTED AND DESIGNED FOR VARIOUS TEMPORARY LININGS CONSISTENT WITH THE ALLOWABLE SHEAR STRESS. SPECIAL CONDITIONS AS PART OF THE STORMWATER MANAGEMENT PLAN, THE STORMWATER CONVEYANCE SYSTEM WAS DESIGNED TO DIRECT THE REQUIRED INFILTRATION VOLUME (ONE INCH x IMPERVIOUS AREA) TO THE INFILTRATION PONDS AND ALLOW THE REMAING FLOW TO BYPASS. THIS WAS ACCOMPLISHED BY CAPTURING THE SURFACE FLOW IN A SUBSURFACE SYSTEM. THE OUTLET PIPE WAS SET TO OVERFLOW WREN THE INFILTRATION POND VOLUME WAS OBTAINED. THE OVERFLOW SYSTEMS WERE EITHER A SECOND PIPE SET AT THE OVERFLOW ELEVATION OR AN OPEN CATCH BASIN (WITH CONCRETE LID) THAT ALLOWS THE OVERFLOW TO PASS THROUGH TO AN OPEN CHP2INEL. SEDIMENTATION CONTROL MEASURES ALL SEDIMENTATION CONTROL MEASURES WERE SIZED BASED ON 1,800 CF/YR/AC OF DENUDED ARE)i WITH A 12 MONTH CAPACITY. ALL WEIR DESIGNS WERE BASED ON THE CONTRIBUTING DRAINAGE AREA AND SIZED ACCORDING TO THE NC-S&E PLANNING AND DESIGN MANUEL. THE PROPOSED MEASURES INCLUDE SEDIMENT BASINS WITH A GRAVEL AND RIP RAP FILTER, DITCH CHECK DAMS WITH PITS AND GRAVEL AND RIP RAP FILTERS, SILT FENCING, DIVERSION DITCHES, GRAVEL CONSTRUCTION ENTRANCES, INLET FILTERS AND OTHER DEVICES/MEASURES AS REQUESTED BY THE INSPECTOR SUPPORTING DATA .,ft.-y - INFILTRATION IMPOUNDMENTS (A0 nershtp in North Corolino) Formerly, Soil 8 Material Engineers, Inc, April 26, 1988 H.

As requested, our infiltration testing was conducted at each of the designated locations to a depth of four feet below the existing ground surface. At each test location, our personnel visually classified the in —place soils and measured the depth to groundwater, if encountered during the field testing work. Representative samples of the in —place soils were also obtained and subjected to laboratory gradation testing in accordance with the American Society f- r_,a Tes wing and Materials (ASTM) test procedure entitled ASTM D-422, "Standard M6thod for Particle —Size Analysis of Soils."

New Hanover County Waste Industries Inc., proposes to construct a truck servicing facility to repair, fuel, wash and store trucks. The proposed site is located approximately 3 miles North of Wilmington on U.S. Highway 421. According to the plans and supporting data, the applicant proposes to construct an office, a shop, and parking areas totaling 3.65 acres of built -upon area. The applicant proposes to construct 3 infiltration basins on the site to collect at least 1 inch volume of runoff. Soil data indicates that infiltration rates are extremely, rapid in this area ranging from 22 gal./hr/ft2 to 110 gal. /hr/ft2 . Stormwater runoff is designed to sheet flow off the parking areas into swales prior to entering the 3 basins. Three monitoring wells and a maintenance plan have also been included in the plans. The site is located approximately 4000 feet from the Northeast Cape Fear River, classified "C-Swampwater". It is recommended that the proposed project be presented to the director for certification that the stormwater runoff from the site poses no threat to surface waters due to the distance to classified waters, and the fact that the applicant has proposed mitigative controls by designing a system which meets the intent of the stormwater regulations. A draft certification form is attached for your review and consideration. If you have any questions, please advise.

As requested, our infiltration testing was conducted at each of the designated locations to a depth of four feet below the existing ground surface. At each test location, our personnel visually classified the in --place soils and measured the depth to groundwater, if encountered during the field testing work. Representative samples of the in -place soils were also obtained and subjected to laboratory gradation testing in accordance with the American Society for Testing and Materials (ASTM) test procedure entitled ASTM D-422, "Standard Method for Particle -Size Analysis of Soils." Based on the results of our field and laboratory testing, the on -site soils consisted mainly of silty sands and clean free -draining sands. The infiltration rates at the three test locations ranged from 22 to 110 gallons per hour per square foot. SBME, Inc. 7650 Market Street Wilmington, NC 28405 H. S.

Williams Division of Environmental Management 7225 Wrightsville Avenue Wilmington, North Carolina 28402 RE: Storm Water Infiltration System Waste Industries, Incorporation Wilmington, N.C. New Hanover County Dear Mr. Williams: We are enclosing three prints of the storm water management plan for the referenced project. Also included is a location map showing the site, which is approximately 4000 feet from the N.E. Cape Fear River. As indicated on the location map, a sand pit operation is located between the proposed site and the N.E. Cape Fear River. We propose to utilize three infiltration basins to retain the first inch of run-off from the impervious areas. The three areas were bored to a depth of eight feet without any indication of reaching the seasonal high water table. Also as per our conversation, the owner has acquired Soil & Material Engineers to perform an infiltration test. The volume of the infiltration basins are as follows: Basin #1 - drainage area = 0.33 acres volume of storage = 1208 cu. ft. basin size = 2.51 x 15' x 32' Basin #2 - drainage area = 1.66 acres volume of storage = 6026.cu. ft. basin size = 4' x 30' x 50' Basin #3 - same as Basin #2 tWilliams Page 2 Flow exceeding the first inch will over flow the basins as shown on the drawing.
