The existing boilers are rated at 400 hp (Boiler #1), 600 hp (Boiler #2), and 600-hp (Boiler #3); the boilers were installed in 1989, 1995, and 1998 , respectively. The boilers normally operate 24 hr/day, 7 day/wk, and 52 wk/yr except for down times during routine maintenance. Twice a year during the July 4th Week and Christmas Week, the boilers are shutdown for maintenance. The three existing boilers combined produce approximately 600 gal/day of boiler blowdown water which is discharged from the boilers at a temperature in the range from 100 to 110 °F. The discharged water drains on a concrete spillway as shown in Figure 1 for approximately 360 ft where it enters a stormwater discharge drain. After entering the stormwater drain, the boiler blowdown discharge travels approximately 450 ft to a stormwater discharge settling pond constructed to prevent discharge of pine bark from the site. By the time the blowdown water reaches the stormwater retention pond, its temperature is approximately equivalent to the prevailing air temperature. The volume of the retention pond is variable because of the bark collected therein; bark must be manually removed from the retention pond several times a year. Figure 1. Boiler blowdown discharge spillway. The installation dates of these boilers were incorrectly listed on the original NPDES application as 1986, 1992 and 1997, respectively. 1 NOTICE OF RENEWAL INTENT New South Lumber Co., Inc. — Graham Plant CoC: NCG500609 A site map is attached to this Notice of Renewal Intent to show the flow of the boiler blowdown discharge across the property to its discharge point at stormwater Outfall #002. 2.0 Addition of a New Boiler The New South Lumber Co., Inc. — Graham Plant has plans to expand their production capacity. To accomplish this expansion, the site hopes to add a new 1,200-hp boiler, an 85.0 X 106 bdft/yr steam -heated dry kiln, and a log wet deck. The facility has obtained Air Quality Permit No. 06740T10, effective September 13, 2006, to install the new boiler and dry kiln; a permit Application No. WQ0030800 for the construction of the wet deck is under review by the NCDWQ. Addition of the new boiler will approximately double the total boiler blowdown discharge to 1,200 gal/day. 3.0 New Boiler Water Treatment System Part of the project to install a new boiler will include the installation of an improved boiler water treatment system. The new water treatment system produced by ANCO will include components that adjust the well water composition to make it more compatible for use in the boilers. Components of the treatment system include a resin -based water softener, a resin -based dealkalizer, and an iron removal filter. Each of these components requires regeneration on a regular basis depending on the concentration of impurities in their feed water, i.e., well water, and the volume of water treated. The regeneration processes require backwash of the resin beds or filter and will result in additional wastewater discharges that we propose combining with the boiler blowdown discharge. 3.1 Dealkalizer Discharge The discharge from regeneration, i.e., backwash, brine draw and slow rinse, fast rinse, of the dealkalizer resin is estimated by ANCO to be 320 gal/regeneration and will contain 1.50% NaC1 and 0.09% NaOH/KOH in the discharge water. ANCO estimates that the resin will need to be regenerated every 1.75 to 2.00 days to purify 1,200 gal/day of boiler water. Thus the discharge from dealkalizer regeneration will amount to 183 gal/day, i.e., 320 gal/regeneration - 1.75 day. 3.2 Water Softener Discharge The discharge from regeneration, i.e., backwash, brine draw and slow rinse, fast rinse, of the water softener resin is estimated by ANCO to be 660 gal/regeneration and will contain 2.73% NaC1 in the discharge water. ANCO estimates that the resin will need to be regenerated every 1.75 to 2.00 days to purify 1,200 gal/day of boiler water. Thus the discharge from water softener regeneration will amount to 377 gal/day, i.e., 660 gal/regeneration - 1.75 day. 3.3 Iron Filter Backwash Discharge The discharge from the backwash of the iron filter to remove particulate matter is estimated by ANCO to be 32 gal/day; the filter is actually backwashed once a week for 8 min at 28 GPM. No chemicals are used in the backwash water. 2 NOTICE OF RENEWAL INTENT New South Lumber Co., Inc. — Graham Plant CoC: NCG500609 4.0 Total Rate of Boiler Blowdown and Treatment Water Discharge The total rate of boiler blowdown discharge is the sum of actual boiler discharge, i.e., see § 1.0 and §2.0, plus the volume of water used to regenerate the boiler water treatment system, i.e., see §3.0. The total rate of discharge from the three existing boilers is 600 gal/day and the estimated amount from the proposed new 1,200-hp boiler is 600 gal/day. The total rate of discharge from the boiler water treatment system is estimated to be 592 gal/day. If the water treatment system discharge is added to the boiler blowdown water discharge, the total rate of discharge will be approximately 1,792 gal/day. 5.0 Types of Chemicals Added 5.1 Boiler Water Treatment Chemicals In a letter addressed to Mr. Gil Vinzani of the NC DWQ dated November 2. 2006, we have previously noted the Department of the chemicals used to treat our boiler water. These chemicals are supplied by ANCO, a division of Chem -Aqua, Inc. and are ANCO- OX 1040, ANCOTREAT 1154, ANCOTREAT 1290, and ANCOSTEAM 2060. The MSDSs for these chemicals are attached to this Notice of Renewal Intent. When we requested that ANCO provide us a completed Biocide Worksheet Form 101 for each of these chemicals, they replied in the attached letter that the subject boiler chemical additives are not biocides and "...the completion of Biocide Worksheet Form 101 is not applicable in this case." 5.2 Dealkalizer Treatment Chemicals The regeneration of the chloride cycle dealkalizer is a three -step process: 1) backwash of the resin with fresh water to remove suspended solids that accumulate on the resin bed during the service cycle; 2) brine draw backwash of the resin bed with a solution of salt (NaC1) and NaOH/KOH (see MSDS for ANCOTREAT 1154) removes the undesirable anions and replaces them with chloride ions; and 3) rinse of the resin bed with softened water to remove excess chloride and hydroxide ions. A more detailed explanation of the process may be found in the attached ANCO Technical Bulletin 4-012, "Alkalinity Removal Using A Chloride Cycle Dealkalizer." 5.3 Water Softener Chemicals The removal of undesirable cations from the well water is accomplished with a sodium cycle softener where the sodium cations on an ionic resin are replaced by calcium, magnesium, etc. cations. The regeneration of this resin is accomplished by backwashing with a brine (NaC1) solution that replaces the trapped undesirable cations. A more detailed explanation of the process may be found in the attached ANCO Technical Bulletin 4-001, "Basic Softener Operation." Additionally, ANCO has provided the attached letter which states that "...the liquid brine and caustic solutions used to regenerate your water softener and dealkalizer are not a biocide." 3 NOTICE OF RENEWAL INTENT New South Lumber Co., Inc. — Graham Plant CoC: NCG500609 5.4 Iron Removal Chemicals There are no chemicals used in the treatment of the iron removal filter. Backwash of the filter on a routine basis with fresh water is necessary to remove particulate materials trapped on the filter material. The iron filter must be replaced when its removal efficiency drops. The need for replacement depends on the results of regular water analysis for iron. 4 BELMONT - MT. HERMON RD.
