The mine is identified as Brickhaven Mine No. 2 (Permit No. 19-08) with 382 acres permitted at the site and 83.5 acres allowed to be disturbed. CSB maintains sediment and erosion control sufficient to meet NCDENR requirements. However, traditional sediment basins may not completely remove turbidity and suspended solids due to the highly colloidal content and poor settling characteristics of the storm water which collects in mining area. As a result of CSB's regard for the environment and community concern a meeting was held with Members of the Moncure Community, Members of the Chatham County Commissioners and Members of the Chatham County Planning Board to discuss Goff Creek water quality issues in November 1997. In addition to that meeting, CSB scheduled a meeting with NCDENR to discuss researching to determine the feasibilitv and nractimlity of additinna] water treatment cnerifirnlly turbidity and suspended solids treatment. Since CSB maintains sufficient sediment and erosion control to meet'NCDENR requirements, additional water treatment exceeds all requirements and permit conditions. Project Description Currently, the mine excavation consists of approximately 50 acres which collects storm water at the lowest portion of the mine. The water is pumped up gradient to a sediment basin which drains by gravity through a brick filter and eventually offsite. Pursuant to the meeting with NCDENR Division of Water Quality and Division of Land Resources, CSB began evaluating alternatives for the additional water treatment including various polymers. Jar tests were conducted to determine the effectiveness of individual polymers. Application of the polymer presented the greatest challenge at the remote mining location. Htially, CSB selected a gel log polymer. Water was pumped from the mining area to a series o f five 100 gallon farm tanks to provide mixing. Each tank contained two gel logs. Water flowed from the farm tanks intn the $ed:rr1ent haa,hn (See Pi4tµreJJ1%lL111Ldty wb`1%,LL Reduction LU Vilas vscived, however11e gel logs accumulated sediment which seemed to affect water treatment and have little impact on suspended solids. As a result, CSB continued to evaluate other alternatives. Additional jar tests were conducted with a liquid polymer (See Attachment A) which is utilized in wastewater and drinking water applications. The jar tests determined the proper application rate and based on pump flow rates an electrical chemical feed pump was set up to introduce the desired amount of polymer for optimum treatment. The same setup for the gel log application was utilized to provide adequate mixing and the polymer was introduced in the uppermost tank. Water flowed into the basin from the farm tanks where flocculation began and colloidal clay particles settled rapidly to produce reduced effluent turbidity and suspended solids. Sediment accumulation in the tanks was minimal. Results T he gel log polymner was success u1 in reducuig turbidity (See Attachment B j although the collection of sediment on the logs and in the tanks make the togs an undesirable alternative for CSB. The liquid polymer is the alternative which worked best for CSB and significantly decreased turbidity and suspended solids {See Attachment Q. Approximately 90,000 gallons per day can be treated with 1.75 gallons or 15 pounds of polymer at a cost of approximately $15 -$20 per day. Conclusion Both alternatives made an impact on water quality, however, the liquid polymer significantly reduced suspended solids and turbidity and worked best for. CSB. As a result, CSB intends to continue the use of the polymer when necessary to treat storm water which collects in the mining area. in addition, the material which collects in the sediment basin will be utilized in brick manufacturing when excavated from the basin. CSB continues to have respect for the environment and community concern as demonstrated by the effectively improving water quality utilizing new and creative practices. phoTaFLo-c Technical Bulletin 10102 - How to Use the PHOTAFLOCTM Gel Cube Sample Kit Tor Log-in-the-S3iream TM Product Selection Neutron Products family of PHOTAFi OCTr gel comprises a complete catalogue of more than twenty water treatment polymers. The Log-in- the-Streamr" sample kit contains several gel cube types selected for their notential effective- ness in your application. The evaluation proce- dure is simple and no expensive equipment is required. We recommend that testing be conducted on - site, as effluent samples may change over time or during transport affecting the validity of the results. Use effluent samples which are repre- sentative of normal operating conditions. If the effluent is subject to periodic variation, testing should be repeated to account for changing conditions. Required equipment includes a large container for collecting effluent, several clear wide mouth jars or equivalent, and a timer (a watch with a second hand is okay). Fill several jars to the same level; about half full. Add a gel cube to one jar and cap. Wait two minutes for the cube to become wet and swell. Shake by holding the jar by the lid and inverting. Count the number of shakes. Stop after five shakes and note the floc size, settling rate, and clarity of the water. Continue in this manner until clear water is observed. Repeat with cubes of each type of poly- mer, striving for consistent treatment of all samples. The best polymers will be the ores that produce iarr e, fast settling tiocs and Gear water with the fewest number of shakes. When thin selection has Lin-, n-n. edl i0 lV 4/I 14GIl,VY►Gli two or three products, retest using the wet cubes from earlier tests, eliminating the two minute wetting period, and shaking two jars side -by -side. Decant the treated water into clean jars, leaving the gel cubes behind. Cap the jar, shake vigorously for ten to fifteen sec- onds and observe. Some reduction in floc size is normal, but the successful product should still produce acceptable water quality on standing for a few min- utes. Difficult to treat effluents may require longer shaking in order to dissolve sufficient polymer for adequate flocculation. Water temperature and quality may affect dissolution rates, and some fragile flocs may not withstand intense or pro- longed shaking. Thus some experimentation may be required to optimize the test procedure for individual needs. Best results are sometimes obtained by segential treatment with two different gel prod- ucts. This approach will often improve clarity or strengthen small or fragile flocs. To evaluate product combinations follow the procedure, then decant, add the second gel cube and continue.
