Mr. Robert Patterson Wetlands and Stormwater Branch North Carolina Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 Subject: NPDES Stormwater Permit Monitoring Plan Permit No. NCS000057 Chemical Specialties, Inc. (CSI) Cabarrus County Dear Mr. Patterson: Chemical Specialties Inc., has devised a monitoring plan for sampling runoff from segregated areas to determine if and where primary contributions of copper and zinc to stormwater occur at the site. During the period beginning on the effective date of the permit (May 1, 2012) and lasting until expiration, analytical monitoring of stormwater discharges shall be performed during a representative storm event. The required monitoring requires grab sampling of a minimum of 5 internal segregated outfalls including stormwater drains and roof discharge drains; which will be sampled bi-annually. Additional areas may be sampled to the further delineate potentially contributing areas. Chemical Specialties, Inc. will evaluate the proportion of the contribution to the total mass of copper and zinc in runoff from the entire site; measurements are to be taken concurrently at stormwater discharge outfalls. Sincerely, .ice.`_ Mark Dwyer Safety, Health and Environmental Manager Attachment PO Box 1330 •5910 Pharr Mill Road • Harrisburg, NC 28075 •704-455-5181 Main Fax 704-455-6507 • Purchasing and Transportation Fax 704-455-5987 Lab Fax 704-455-1123 • Accounting and PoleCare Fax 704-455-1940 Engineering Fax 704-454-5348 itlGS poop s''> Copper and Zinc Stormwater Sampling Protocol 1. Representative Samplin¢ Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Analytical sampling shall be performed during a measurable storm event. Samples shall be taken on a day anytime that is characteristic of the discharge. All samples should be taken before the discharge joins or is diluted by any other waste steam, body of water, or substance. Monitoring points (minimum of 5) have been identified by a team of qualified and experienced personnel with consideration given to material storage and handling areas. Additional source points to be sampled may be added to, or removed from the sampling agenda to further segregate potential point sources, or as per defined in the current plan. 2. Recording Results For each measurement or sample taken pursuant to the requirements of this permit, Chemical Specialties, Inc. shall record the following information (40 CFR 122.41). a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling of measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses, including flow volume and total event volume. 3. Records Retention Copies of analytical monitoring results shall also be maintained on -site along with the Stormwater Pollution Prevention Plan. 4. Sampling Analysis Results The sampling results will be evaluated and appropriate actions will be implemented including Best Management Practices. Corrective actions will be evaluated, via sampling program, after implementation to determine their effectiveness. �VE NOV 1 3 2012 Sampling Area #1 Tanker Parking (at gate valves) Cu 0 Zn 0 . 0% 0% #2 ACQ Tank Farm roof drain (NW corner of roof) 0 0 0% 0% #3 Storm drain behind #4 warehouse 0 0 0% 0% #4 Main drain by-pass at QC Lab (6" pipe) 0 0 0% 0% #5 Run off pipe at fire water tank 0 0 0% 0% #6 Bldg. 1 (NE Corner) 0 0 0% 0% #7 Bldg. 1(NW Corner) 0 0 0% 0% #8 Dock #3 (S side of bldg.. 36) 0 0 0% 0% #9 Downspout in front of T-142 (E of AA plant) 0 0 0% 0% #10 Downspout in front of Bldg.23 0 0 0% 0% #11 Downspout pipe west of T-138 (Chiller room area) 0 0 0% 0% #12 Downspout at SW corner of Bldg.24 0 0 0% 0% #13 Drain at North side of Bldg. 230/231 0 0 0% 0% #14 Downspout at W side of loading dock roof(Bldg. 230) 0 0 0% 0% #15 French drain (open end) SE corner of Bldg. 231 0 0 0% 0% #16 Curb -side drain at ACQ drive (North/upstream drain) #17 Curb -side drain at ACQ drive (South/downstream drain) #18 Outfall #1 0 0 0% 0% 419 Outfall #2 0 0 0% 0% #20 Rocky River (upstream) 0 0 0% 0% #21 Rocky River (downstream) 0 0 0% 0% Analytical Monitoring Requirements Discharge Characteristics Units Measurement Frequency Sample Type Sample location Copper, Total Recoverable mg/L semi-annual Grab #1-#21* Zinc, Total Recoverable mg/L semi-annual Grab #1-#21* Monitoring Schedule Monitoring period Sample Number Start End Year 1- Period 1 1 1-May-12 31-Dec-12 Year 1- Period 2 2 1-Jan-13 30-Jun-12 Year 2 - Period 1 3 1-Jul-13 31-Dec-13 Year 2 - Period 2 4 1-Jan-14 30-Jun-14 Year 3 - Period 1 5 1-Jul-14 31-Dec-14 Year 3 -Period 2 6 1-Jan-15 30-Jun-15 Year 4- Period 1 7 1-Jul-15 31-Dec-15 Year 4 - Period 2 8 1-Jan-16 30-Jun-16 Year 5 - Period 1 9 1-Jul-16 31-Dec-16 Year 5 - Period 2 10 1-Jan-17 30-Apr-17 *Sample locations may be changed/added/removed as determined beneficial to further identify possible contributing areas. _ _ I 1 2 3j 3 6 'r 1U1 14 15 16I 17� 1 191 20 2y 2 ?:3 251 27 281 1 291 30 PLANT NORTH k TRUE NORTH d 1 • ��u Ill�l�lllu � ��Illl�lllm ®I�� r•, , y� >�ry7�1y� ----------------------------•----------------------------------------------------------- ------ m--------- ---------- -----------rim-effiru:Uli'L�Y' -� H ill ------ -------------- DA1Y-If ►��a ,A4eQ►.� ,��1�-----------■ --__-ate.-•�.r-�.�r.--�-' •- �� ' -- -_-, _--. .i� r 7•�� I, FOR 10410 • ► � • - � r a• a ` 1 - L__J Ll I. `dal �I �� J �� .®__ I �2II,,,,� _ - - ♦♦♦♦♦♦♦� ' �� . ��1 ls.
