Dear Mr. Parlier:

Subject: NPDES Permit Modification
Linville Resorts WWTP
Return #2023
Avery County
The Division received your request for NPDES permit modification on September 1, 1998. A
review of the submitted application indicated that no engineering alternatives analysis was provided.
Title 15A North Carolina Administrative Code 2H .0105 (c) (2) requires submittal of an Engineering
Alternatives Analysis with all new applications for discharge. The request for an additional 100,000
GPD of wasteflow is an expansion of the existing facility and would be considered new flow. Therefore,
the modification is being returned to you. The alternatives analysis should address whether the
expanded wastewater treatment plant will be able to meet tentative effluent limitations for BOD5 and
NH3 in the range of 3 to 9 mg/1. In addition, a quarterly chronic toxicity limit of 13% would have to be
met since the new wastewater could contain metals or toxicants from hospital waste.
As you are aware, it is the Division's mandate to permit the most environmentally sound
wastewater treatment system of the reasonably cost effective alternatives. Subsurface or irrigated
disposal systems are typically considered to be more environmentally sound alternatives than discharge
options. In that light, the engineering alternatives analysis is meant to provide justification for a surface
water discharge alternative through a comparison of that alternative with other non -discharge options.
Enclosed is a copy of the Division's Guidance for the Evaluation of Wastewater Disposal
Alternatives. In preparing the alternatives analysis, the engineer should identify all possible disposal
alternatives. For example, the option of a regional connection of the proposed Avery County Hospital to
the Newland WWTP should be discussed and evaluated. Also, connecting the proposed hospital to the
existing system without expanding the wastewater treatment plant should be considered. Once all
alternatives have been identified, they should be evaluated from both a technical as well as economic
standpoint. As part of the analysis of land -based disposal alternatives, a detailed soil scientist report
should be provided. The soil scientist report should include at a minimum the following pieces of
information:
• a copy of field notes and boring log information
• a soils site map overlain on a topographic map
P.O. Box 29535, Raleigh, North Carolina 27626-0535 Telephone [phone]/FAX [phone]

ti
• description of soils characteristics to include texture, structure, soil wetness and mineralogy
• characterization of the depth of soil to 48" or to a restrictive horizon
• soil loading rate recommendations.
The on -site soil survey should include enough soil borings to adequately characterize the site.
Additionally, justification should be provided on the number and location of soil borings completed.
Generalized county soil survey maps are not adequate for the evaluation, but may be used as a reference
tool to plan the field work required for the evaluation.
The economic analysis should include a present value of costs determination for each identified
alternative as outlined in the attached guidance document. All costs used for the present worth analyses
should be referenced with cost sources included as attachments.
If you have any questions regarding this matter, please contact Jacquelyn Nowell of my staff at
[phone], extension 512.
Sincerely,
ffk/A. Preston Howard, Jr., P.E.
