I have received your letter dated 19 May.1997 and Ms. Linda Lewis' letter to Mr. Jim Honeycutt, P.E. about our Stormwater Management Application dated 30 April 1997. After my telephone conversation with Ms. Lewis I would like to formally protest several requirements and requests contained within her letter. First I would like to assure you that we are not in the habit of violating any requirements or regulations of the great State of North Carolina. However, as we attempt to expand, allowing the employment of more North Carolinians it is quite evident that the State of North Carolina Department of Environment, Health, and Natural Resources has other plans for our state. Ms. Lewis has asked several valid questions about the application submitted for a Stornwater Management Permit Application. However, after reviewing all her requests, I question whether the application and plan were reviewed at all. First, if you are not familiar with the location of our site, it is exactly five (5) miles north of the western foot of the Isabel Holmes Bridge in Wilmington. The topography of our land is extremely sandy and elevated with irrigation being the main concern if you wish to have any vegetative cover to survive. Ms. Lewis has asked for a more detailed vicinity map. On the drawing attached to our application it clearly shows that our facility is exactly 1306.14 feet south of the New I lanover County Landfill entrance on Highway 421 North our cast property line is the New Hanover County Landfill. We have a sign measuring 10 feet high and 10 feet wide (permitted) on the highway showing our location. Also, according to your letter our site "vas krisited on 16 May 1997 by a member of your office. Undoubtedly he had no problem funding the site.

We complied with construction of art infiltration basin and plans to insure that, any stormwater runoff from our property is channeled to this basin for infiltration back into groundwater. After receiving a copy of Ms. Lewis' letter to Mr. Honeycutt I talked to her at length about her Q request for additional information and re ements. he c arced to me that one need for a p` jr spreader mechanism was to insure dint. cdimrnt n� into the basin would be evenly \Q 0 distributed to maintain the basin's original design characteristics.

CI�r�E/1f ��//J !A SZ,/ S Originally we wished to use this basin as a landscape enhancement until we were informed that it would not hold water unless it was lined with a synthetic material or clay to stop the water from being absorbed into the ground. If you cannot build a basin on site that will hold water why do we need all this additional wasted expense?

Before pouring the foundation for our present facility we hauled water onto the property fit 7,500 gallon tank trailers to compact the sand to make a better foundation.

If this is a State requirement according to your letter, why should I contact New Hanover County to find out why other companies and individuals do not, have, to comply with your requirements? I would like to document as best I can the costs associated with compliance for construction of the basin and Ms. Lewis' additional requests.

Lewis reggiremen fora spreadernechanism will be. Therefore, lie cannot give us an estimate of what it will cost to design one much less construct. it. $11,200.00 could purchase equipment for an employee to use deriving wages. The same amount used to comply with a requirement applied without common sense will derive $ 0.00. The title of your office suggests that its purpose is to protect the Natural Resources of the Great State of North Carolina. One of the greatest natural resources we have is the citizens of North Carolina. Eliminating or stifling the growth of companies providing employment and additional tax revenue is not protecting the citizens of the state. Hanover Towing has been proactive in improving the Natural Resources of the State of North Carolina. We have made many donations to the North Carolina Department of Environment, Health, and Natural Resources Division of Marine Fisheries. To date we have donated three (3) tugs and five (5) barges to be used in artificial reef development. The last barge donated was C donated prepared, delivered and sunken on the reef at the expense of Hanover Towing with no expense to the State. We could have scrapped all of this equipment and realized revenues from the sale. My wife and I are regular participants at the Area Contingency Plan Meetings. Local Emergency Planning Committee Meetings and have donated hundreds of hours of volunteer service to New Hanover County. Hanover Towing was the first privately owned corporation to voluntarily participate in the Preparedness for Response Program enacted by the Oil Pollution Act of 1990. Cost for our participation was more than $40,000.00. Our actions indicate our concern for the environment and New Hanover County. I respectfully request that you review Ms. Lewis' requests with a measure of common sense and call me at your earliest convenience to discuss this matter. Sincerely. W. W. Murrell, ) .

The project was submitted on April 30, 1997, and I did a review on May 7, 1997. The comments included requests to add a distribution device into the basin, and a monitoring well. The permit has not been issued. Mr. Murrell has of course, already constructed the project, and now refuses to do the two things outlined above. He states that "no water will ever get to the pond due to the sandy nature of the soil and he will not put in a monitoring well for a system that won't have any water in it". I tried to explain that these were permit requirements, and that I did not have the authority to waive them. He also spoke about neighboring developments and why weren't they required to do anything, and so on. I will look into those allegations. I told him that he needed to speak to Rick. Unfortunately, Rick is not here today, and Mr. Murrell is going on vacation tomorrow, so I had to give him your name and number. Sorry about that, but he would not listen to me at all. You know where to find me if you need help.

Murrell, This correspondence wit serve to Present findings and calculations to be utilized in designing of the on -site storm water infiltration Pond. Two test Pits were excavated utilising a baWw. Each pit was excavated dawn to aPProximately nine to ten feet deep. Peet Pit P-1, IMM" new the southeastern comer of the proposed infiltration pond, was found to be represented by SOW* foamy send grading Into a fine to medium grained sand. No evidence of seasonal high water table conditions or colors were identified; however, soll wetness conditions were identified at epprorimetety ten feet deep. Test Pit P-2, located near the northieasteM Property oarwr, was also found to be represented by slightly loamy sand grading into a fire to medium grained sand. No evidence of seasonal high water table conditions or colors were identified in P-2. Soil wetness Conditions were also Mentified at apMwimately ten feet deep in P-2. A soil sample was taken from each test pit at appzoxkrwtely ens feet deep. Each sample VMS tested in general accordance with the Amencoi Society for Testing end Materials (ASTM) test procedure 0-422, entitled'Swxuw Test Method for Particle -Sim Analysis of Soils.° As presented in the attached laboratory report, both samples vw(e found to be fine to medium sand. Grain size sieve analyses of both samples were famd to apprailmately corefa6e *0 each other (+1-10%), suggesting consistent conditions under the proposed pond location. Hydraulic eonduuCovify was determined by first establishing a mean value for the fine and medium grained sand sizes. The hydraulic conductivity value was catmdm* utllizkg' know values for specific grain sizes. The hydraulic conduct" for the area of the rmrthsestsm property comer was determined to bo approximately 11.88 inches per hour.
