Distribution of Alum Residuals
Gaston County
Dear Mr. Rhyne:
In accordance with your application received on June 27, 2000, we are forwarding herewith
Permit No. WQ0018688, dated November 8, 2000, to the Town of Dallas for the operation of a
program to distribute/land apply residuals from potable water treatment processes. The product is an
alum residual that is generated from the treatment of raw water from the South Fork of the Catawba
River.
This permit is being issued to approve the distribution/land application of the residual on
unspecified fields. Note that the residuals shall not be referred to as "biosolids" or as meeting Class
A requirements as stipulated in 40 CFR Part 503 in marketing them to potential recipients.
This permit shall be effective from the date of issuance until October 31, 2005, and shall be
subject to the conditions and limitations as specified therein. Please pay particular attention to the
monitoring and reporting requirements contained in this permit. Failure to establish an adequate
system for collecting and maintaining the required operational information will result in future
compliance problems. Upon renewal, the conditions of this permit may change due to alum residuals
policy issues.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to Chapter
150B of North Carolina General Statutes, and fled with the Office of Administrative Hearings, 6714
Mail Service Center, Raleigh, NC 27699-6714. Unless such demands are made this permit shall be
final and binding.

amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Town of Dallas
Gaston County
FOR THE
operation of a program for the distribution/land application of alum residuals from the treatment of potable
water. The program shall result in the distribution of up to 290 dry tons per year of residuals from the sources
listed in Condition 112, with no discharge of wastes to the surface waters, pursuant to the application received
on June 27, 2000 and in conformity with the project plan, specifications, and other supporting data
subsequently filed and approved by the Department of Environment and Natural Resources and considered a
part of this permit.
This permit shall be effective from the date of issuance until October 31, 2005, and shall be subject to
the following specified conditions and limitations:
PERFORMANCE STANDARDS
The distribution/land application of residuals program shall be effectively maintained and operated
as a non -discharge system to prevent the discharge of any wastes resulting from the operation of
this program.
2. This permit shall become voidable in the event of failure of the residuals program to adequately
protect the assigned water quality standards of the surface waters and groundwaters.
The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface or groundwaters resulting from the operation of this programs.
4. In the event that the residuals program is not operated satisfactorily, including the creation of
nuisance conditions, the Permittee shall take any immediate corrective actions as may be required
by the Division of Water Quality (Division).
5. Diversion or bypassing of the untreated residuals or leachate from the residual treatment facilities
is prohibited.
6. All leachate must be reused as a wetting agent for the processing of residuals or routed to the head
of the treatment plant.

7. The following buffer zones shall be maintained:
a. 100 feet from any public or private water supply source, waters classified as SA or SB, and
any Class I or Class H impounded reservoir used as a source of drinking water for both
methods,
b. 100 feet from any streams classified as WS or B, any other stream, canal, marsh or coastal
waters and any other lake or impoundment for surface application,
c. 50 feet from any streams classified as WS or B, any other stream, canal, marsh or coastal
waters and any other lake or impoundment for subsurface application,
d. 50 feet from property lines for both surface and subsurface application methods;
e. 50 feet from public right of ways for both application methods,
f. 25 feet from downslope interceptor drains, surface water diversions, groundwater drainage
systems and surface drainage ditches for both application methods.
A copy of this permit and a spill prevention and control plan shall be maintained in all residuals
transport and application vehicles.
9. No residuals shall be stored at any location other than at the water treatment facility at any time,
unless approval has been requested and obtained from the Division.
10_ Specific residual application area boundaries shall be clearly marked prior to and during
distribution/land application.
11. Maximum slope for the distribution/] and application of residuals shall be 10 percent for surface
application and 18 percent for subsurface application.

permit:
Permit Volume
Source County Number (Dry Tons/Year)

3. All residuals shall be adequately stored to prevent leachate runoff until treated. The finished
product may be placed on a concrete pad, placed under shelter or covered until such time as it is
distributed/land applied. If an alternate storage site is to be used, approval must be obtained from
the Division.
4. No other residuals other than those specified under Condition ld 2 above may be distributed/land
applied. The Permittee shall request and obtain a permit amendment from the Division for each
additional residual source prior to acceptance of that residual.
5. For residuals to be distributed/land applied, the residuals shall be essentially pathogen -free, as
evidenced by the testing of seven (7) separate and representative samples of the residuals for the
presence of fecal coliform in accordance with Condition In 3 of this permit. Distribution/land
application of the residuals shall be strictly forbidden if any sample results in a fecal coliform
density of 1,000 most probable number (MPN) or coliform forming units (CFU) per gram of total
