Additional Information for Questions McCarthy Improvement Company, Inc. McCarthy Warren County Concrete Batch Plant 8) Description of Industrial Activities The facility will be a temporary concrete batch plant located on a 4.39 acre parcel ]eased by McCarthy Improvement Company located near the intersection of Interstate Highway 85 and Ridgeway Drewry Road in Warren County. The site was previously undeveloped pasture land. The McCarthy Improvement plant will provide the concrete for a repaving project in Interstate Highway 85. 12) Type of Wastewater A combination of wastewater and stormwatcr will be discharged from this facility's outfall intermittently during the 18 months the plant is expected to be located at this site. Wastewater will be comingled with stormwater only when the plant is in operation. The plant will operate intermittently during the 18 month on site. On the days the plant is operating the wastewater described in Attachment B will be generated. 16) Recycling system This plant will be using a series of'three settling pits to treat and recycle the washout water from the truck bed washout area. The plant anticipates approximately 200 washouts per day. Each washout will use approximately 50 gallons of water. The anticipated volume of wash water generated will be approximately 10,000 gallons per day, which will be contained and recycled through the settling pits. The total holding capacity of the settling pits will be approximately 90,000 gallons. The waste water from the third pit will be recycled as washout water and used for dust suppression on the vehicle travel routes on the site. Eighteen inches of freeboard will be maintained in the third washout pit to accommodate a 10 year rain (5.7 inches) event over the three ponds. 18) Wastewater Treatment Alternatives Review c) Closed -loop Recycling System (15A NCAC 2T .1000) (2) Construction of a CLRS meeting NC standards 15A NCAC 2T .1000 is not technologically feasible. The small size of the site does not provide the space necessary to construct the CLRS to meet the NC standards. (3) The plant will be located at this site for approximately 18 months. The limited operational time at the site does not justify the expense of constructing the CLRS. Additionally, this project, as with most similar projects, has a fairly short lead time and the six months or more that would be necessary for the design, approval, and installation of a CLRS is not available. (4) The time and disruption of constructed infrastructure required for the design, approval, and installation of a closed -loop recycling system that will be utilized for the treatment of a limited amount of wastewater the next I8 months cannot be justified. (d) Surface or Subsurface Disposal Systems (i) Wastewater from the recycling system can be used for dust suppression and a skimmer basin will reduce solids in the water discharged to the surface. (ii) Water from the recycling system described in Question 16 will be used for dust suppression when the residual suspended solids in the water make it impossible to continue recycling the water. Also, all wastewater will be contained within a skimmer basin which will allow a significant portion of the suspended solids to settle out before being discharged to the surface. (iii) Both methods of surface disposal are feasible and will be implemented. 19) Best Management Practices (BMP) (1) Perimeter containment/diversionary berms and a drainage Swale will direct the combined stormwater and wastewater discharges to the skimmer basin. (2) A skimmer basin at the cast end of the site will contain the combined stormwater and wastewater to allow a significant portion of the suspended solids to settle out of the water before being discharged. (4) All disturbed surfaces within the site boundaries will be stabilized with 4 to 6 inches of graded aggregate base (GAB) or vegetated with permanent vegetation, (5) All parts and maintenance oil, grease, and fluids will be stored inside the parts trailer at all times. (6) Diesel fuel kept on site to fuel material handling equipment will be stored in a 1,000 gallon double -wall tank and used oil from minor maintenance is stored in a 75-gallon double -wall tank. Attachment B — Description of Processes Producing Wastewater Three processes at this facility will potentially contribute wastewater to the effluent from the outfall. Wastewater Source 1: Wastewater Source 1 is the concrete batch plant drum. The drum on the plant will be washed out once per day on days he plant is operational. The wastewater produced from each washout is approximately 800 gallons per day. Wastewater Source 2: Wastewater Source 2 is the truck bed washout used to washout the beds of the dump trucks used to transport the concrete to the location being paved. The plant anticipates producing 200 truckloads per day and the trucks will be washed out after each trip. Each washout will use approximately 50 gallons of water. The anticipated volume of wash water generated will be approximately 10,000 gallons per day, which will be contained and recycled through a series of three pits designed to allow suspended particles to settle out of the wash water. The combined holding capacity of the pits is approximately 90,000 gallons. The water in the third pit will be recycled as wash water or used for dust suppression on the site. Solids will be removed from the pits when they occupy one half of the designed holding capacity of the pit. The solids are dried and properly disposed of. Wastewater spilled or leaked from the recycling system or the washout area would flow to the skimmer basin and ultimately be discharged to the surface. Eighteen inches of freeboard will be maintained in the third washout pit to accommodate a 10 year rain (5.7 inches) event over the three ponds. Wastewater Source 3: Wastewater Source 3 includes the aggregate and sand stockpiles. The aggregate stockpile will be wetted using a lawn sprinkler and hose. The sprinkler will be rotated around the stockpile during the day to cover all parts of the pile. Wetting the aggregate stockpile is done to produce an evaporative cooling of the stone. The evaporation of the water during this sprinkling process reduces the volume of water that ultimately flows away from the stockpile. Wetting is not used on the sand stockpile. Per DOT specifications both the aggregate and sand arc washed prior to being delivered to the site, reducing the potential fines in stormwater runoff from the area covered by the stockpiles. Wetting of the aggregate stockpile will be conducted up to 24 hours per day when the plant is operating. The wastewater from the aggregate stockpile will consist of water from the wetting of the stone and stormwater that falls on the pile. Wastewater from the sand stockpile will consist of only stormwater that falls on the pile. Stormwater and wastewater from both stockpiles will flow to the skimmer basin and ultimately be discharged to the surface, - Energy, Minerol and Land Resources ENVIRONMENTAL QUALITY July 28, 2017 Mr. Kevin Crusa McCarthy Improvement Company 590 Means Street NW Atlanta, GA 30318 ROY COOPER Gorernor MICHAEL S.
