I have attached our written response to the Notice of Violation referenced by (NOV-2022-PC-0583) regarding our Stormwater Permit NCS000291. Included in this response you will find an amended copy of our SPP, a feasibility review to reduce Stormwater contamination for 2022, the written response to the violations labeled stormreply and a pdf file with our documentation for the corrective steps we have taken. As stated earlier, we are having issues with our email, so I will also duplicate this from another email address. Sincerely, Rodney McRae McRae Woodtreating Inc. McRae Woodtreating Inc. 105 National St Mount Gilead, NC 27306 It has never been our intention to be out of compliance in any way with regards to our stormwater permit. I believe our lack of compliance largely rests upon my shoulders due in part to my misinterpretation and the combined added pressure of the pandemic and associated challenges. With regards to my misinterpretation, I had asked a question many years ago regarding a drought period and the ability to get a stormwater sample. The intent of the question was regarding to what lengths I should go to obtain a sample. A paraphrase of that question would have been, "It seems like the only time it has rained lately is either at night or on the weekend and I have not seen any significant rain that would meet the definition of a representative stormwater event to get a sample, is this ok or should I be more determined to get a sample by coming in the middle of the night, etc?" A paraphrase of the answer was that "We are more concerned with you following BMP to prevent stormwater contamination than you collecting the sample exactly before the specified monitoring period ends." As a result, I interpreted that to place more emphasis on making sure we were doing our part not to contaminate than I did documenting what had been done. I am not in any way trying to shift blame or skirt my responsibility, but rather acknowledge that I misunderstood. As we have always strived to be responsible and minimize our risk of stormwater contamination, the majority of the issues Mr. Lawyer pointed out were regarding documentation. Per Mr. Lawyer's evaluation and corrective guidance, I recognize that the documentation is equally important. Secondly, with any small business, managers are often required to wear many hats. As a result of the pandemic and all the new challenges it created to keep the business going and employees safe (including my father who is 82), 1 let all those pressures affect my remembrance to document what we were already doing. Mr. Lawyer pointed out that I may be doing all of the requirements with excellence, but the burden of proof is to document what we are doing. Similarly, Mr. Lawyer reminded me that even during a drought as in my above -mentioned example, we are to document that no representative stormwater event occurred during the monitoring period per the requirements of the stormwater permit. As a result of Mr. Lawyer's site inspection, we have addressed each of the noted violations and made changes to the Stormwater Prevention Plan to correct this going forward and prevent any further violations. Similarly, we are already in the habit of documenting more information than is required for our third -party inspection and assays of our treated lumber. I have taken corrective action to apply this same type of diligence to the documentation required of our permit. As a result, I have addressed the documentation issue with our employees and assigned documentation procedures for the required tasks. I do not take any of these requirements lightly, we ask for the opportunity to correct the violations and welcome any feedback to ensure all the necessary corrections have been made. I would also like to add that we do currently have a stormwater analysis kit waiting on site for a representative stormwater event to occur. The kit has been on site since before Mr. Lawyers visit. I had hoped that the remnants of Hurricane Ian would produce opportunity to gather a sample, but it did not produce enough flow to collect a sample at the Outfall site. At the time of this writing, there is a 60%/90% chance of rain Monday day/evening October 31st. In the event that .we do see a representative stormwater event on that day, that sample will be expediently sent for analysis along with the proper documentation. We appreciate your understanding and assistance in bringing McRae Woodtreating back to compliance with the Stormwater Permit. Sincerely, Rodney McRae McRae Woodtreating Inc. Stormwater Pollution Prevention Plan 1. This plans covers the physical facility known as McRae Woodtreating Inc. which has a physical address of 105 National Street (we were formerly referenced at.Julius Street is the name of our private drive. The 455, Julius Chambers Avenue is still the primary highway in front of the Iplant which is also known as NC Hwy 10.9 except as designated inside of the city limits.: This facility currently pressure treats southern yellow pine with the preservatives CA-C which is branded under the trade name Preserve, and EL-2 which is branded under the trade name Ecolife both by the Viance Corporation. a. Please see the following attached map labeled Al-A5 showing the facilities` general location including Outfall site. b. All major bulk storage tanks are positioned on the facility such that spills would be contained in a concrete bulk storage area located at the base of a sloping concrete drip pad and under the primary and secondary work tanks. In other words, this facility was built with concrete bulk storage as secondary containment in the event of a major spill such that there is enough storage space to contain all of the chemicals stored in the bulk storage tanks. All employees are instructed about safe handling practices of the bulk storage chemicals and what to do in the event of a spill. The facility is set up so that lumber is loaded and unloaded from the same tram for the treatment cylinder with one side designated as the loading side and the other designated as the unloading side. The tram is located at the base of the slope of the drip pad such that any chemical that drips off the lumber would return to a storage trough. From the storage trough it would eventually be pumped back into the primary work tank where the solution strength is constantly monitored so that the recaptured solution strength can be factored and diluted accordingly. After the wood has been unloaded from the tram, it is required to stay on the drip pad until there is no longer any visible dripping. Furthermore, because of the treatment process, the chemical actually binds to the wood and when combined with a long final vacuum there is very little residual left to drip. Trace amounts that remain would be derived from the principal components of CA-C, EL-2, Supatimber H.E., Moldex 45 and ACQ-AF. In their respective order the list refers to the preservatives, mold deterrents and an anti -foam solution with the primary chemicals coming from the preservative in the form of copper. A full list of chemical composition is available from the msds sheets which are on file in our CA-C and Ecolife Operators' Manual stored on the premises or is also available from the Viance corporation. Other possible contaminants to storm water would be any fluids leaking from shipping machinery (forklifts, trucks, etc.) in the form of gasoline, diesel, antifreeze, hydraulic fluid and oil. All of our sludge/hazardous waste is handled by our chemical supplier (Viance) through Terra Storage Facility. This waste is typically generated from mud which accumulates in our collection trough over time. None of this waste comes into contact with any outside stormwater runoff as this trough is at the base of the slope of the drip pad. c. Please refer to the attached site map labeled 61-63. d. We have had no significant spills or leaks over the past seven years. e. We are currently using Waypoint Analytical (Formerly Prism Laboratories, Inc.) at 449 Springbrook Road in Charlotte, NC to monitor the presence of contaminants in the stormwater and we have implemented a plan to monitor the stormwater as per the requirements of the permit on a semi-annual basis. f. Documentation policy regarding analytical reporting has been amended to include first available date of arepresentative stormwater event during business hours for each of the required monitoring periods. As well as documentation for a lack of a representative stormwater event during a; monitoring period. 2. From day one of initial start-up this plant has been designed to receive and store materials necessary for the treatment process such that any exposure to stormwater runoff would be minimized. Even the off loading of bulk chemicals is done with the tanker parked on the drip pad such that in the event of a spill the material would be contained. a. Refer to the following attached photographs for illustrative purposes of material handling and storage. With the exception of fueling, which meets the exception requirements due to the size of the tanks, all other contaminant risks to stormwater runoff have been minimized. b. All materials used to pressure treat the southern yellow pine are stored such that they have secondary containment. Refer to the attached pictures for illustration of this secondary containment. c. 1 Lumber is not permitted to be removed from the drip pad area until all visible signs of dripping have ceased. 2 Filling of the bulk storage tank for CA-C from the tanker must be done with the tanker parked on the drip pad. 3 Refueling of trucks and forklifts from the 2 (500 gallon) above ground tanks (below threshold for secondary containment) must be done with someone present at pump. 4 All bulk storage totes (EL-2) must be stored in their designated covered location which channels to the secondary containment trough. 5 Spill kits and absorbent pads must be kept near their respective chemicals to facilitate quick clean up in the event of a spill. 6 All machinery is to be maintained and inspected for leaks which could impact the stormwater runoff. 7 Currently, monitoring of the stormwater for contaminants is to be done 'semi- annually, in accordance, with the, Storm awater Runoff Permit. If the requirements of the permit require the frequency to be increased the SPP is to. be updated'. with amended requirements: 3. With regard to spill prevention, all employees are trained as to the requirements to properly handle all chemicals used in the treatment process. This facility utilizes basically four main chemicals. The CA-C (preservative) is brought in by tanker and the tanker is required to be off loaded while parked on the drip pad. All hose connections thereby also run across the drip pad so that any leaks would end up in the containment trough. The CA-C is stored in a steel tank above concrete secondary containment and is pumped and handled by mechanical means to the work tanks where all of the process is located over the concrete containment area. EL-2 is handled in totes (250 gallon) and once unloaded from the truck is transported on the drip pad to its storage room where any spill would run to the containment trough. Supatimber H.E. and Moldex 45 (mold preventative) is handled in totes and is positioned near the containment area such that spills would also end up in the concrete containment area. This chemical is acidic and a spill kit / neutralizer is on site beside the mold preventative to neutralize the acid. The fourth chemical is diesel fuel and it is stored in 2 (500 gallon) tanks (one tank is for on road use and the other is for off road use). The diesel fuel tanks are below the threshold for secondary containment requirement but we have spill pads on site in the event of a spill and all refueling is to be done with an employee present to prevent unmanned emptying of the tanks if the hose were to become dislodged or ruptured. We also have a contingency plan in place with contact information posted on entryways in the event of major spill that is on file as well. 4. All plant machinery necessary for the treatment process is maintained and inspected per the manufacturer requirements and recorded maintenance is kept on file. This also includes the lift trucks and flatbed trucks. Furthermore, each flatbed truck and lift truck is given a walk around inspection on a daily basis with documentation. If the machinery is currently in service, any leaks or repairs needed are performed on a timely basis.. We also inform any owner/operator which presents in a third party vehicle for loading if we notice any obvious leaks to their equipment. Routine sweeping and inspection of the drip pad is done on a monthly basis. All employees are encouraged to maintain overall appearance of the yard and premises with cleanliness, trash pick-up and yard maintenance . 5. Team member training with regard to spill response, preventative maintenance, safety and stormwater runoff is recorded in Table A. 6. All employees are responsible to ensure that all equipment is properly maintained and that stormwater pollution prevention protocol is followed. Rodney McRae is responsible for the coordination, development and implementation of the plan. 7. As of October2022, this document is considered to be our stormwater pollution prevention plan and any revisions/amendments will be documented as such to reference this current plan. 8. Refer to Table B for a record of facility inspections. 9. Refer to the written NC Stormwater Reporting Form for a record of stormwater runoff monitoring and qualitativeobservations. As the electronic reporting service becomes fully operational results are to be recorded electronically.. Also, refer to attached documentation from the analyzing lab. All plant and vehicle maintenance is recorded in our plant maintenance log and is kept on file in the office. 10. Refer to Table C for a record of lift truck inspections. 11. Refer to Table D for'a record of flatbed truck inspections.

T e III r L.... i !i I i 2022 Feasibility of Reducing Contaminants to Stormwater Runoff As has been the case for many years, we have discussed the possibility of adding additional shelters to house treated lumber. Based upon BMP we are already following, we believe the most logical and best step to reducing any significant rain contact would be to add additional shelters until all of our treated lumber is stored under shed. Housing treated lumber under a shed not only prevents direct rain contact but also reduces direct sunlight exposure which can facilitate warping in the top layers of packed lumber. This would be a value added benefit as well as reducing possible contamination. We have added, a 40x70 lumber shed to our facility since our last inspection in 2011. This shed houses our 2x4 through 2x10. Currently, our top three options we have considered are as follows. The first option would be to construct a removeable roof that is slightly larger than each length of lumber. This removeable roof would be set to the side with a forklift and then placed back on the remaining stack after the desired pack had been obtained. This option is often used as additional cover where covered storage is limited. However, this option does dramatically affect the time required to load trucks and runoff reduction would be dependent on correct placement of the removeable roof by the lift driver. While this option may be the least expensive, we believe this option it not an efficient choice at the present time, as we handle so many different grades and sizes of lumber and the reduction to contamination would not be as significant as a permanent structure. A second option would be to add a continuous line of pole sheds that span the perimeter of our current lot. This option would allow us to keep our same basic configuration with a minimal amount of disruption of our daily workflow to construct. Based on a current estimate (October 2022), construction cost would exceed $100,000. However, due to the narrowness of this option, we do not believe exposure to blowing rain would be as effective as a larger consolidated structure. A third option would be to add two more sheds including asphalt or concrete at the 40x70 size. We believe this option would be the most efficient to virtually eliminate our stormwater contamination risk. This is the option we hope to be able to construct at some point. Using a current estimate (October 2022) from a local contractor that constructed similar storage at a nearby lumber facility, the cost would exceed $140,000. We do not list the above three options as being all inclusive, but we believe they are some of the most cost effective solutions. As stated above, due to the addition of our most recent shed which does contain some of our fastest moving items, we have seen a reduction in damaged and warped lumber. Because we are a small family owned company, we do believe in investing for our future as our finances will allow. Reducing our stormwater contamination risk and increasing the shelf life as well as protection of our lumber are things worth investing in. We are hopeful that we will be able to add more storage space in the near future such as the third option or something similar that may be more financially achievable.
