Dear Mr. Gottschalk:
In accordance with your permit application package received on September 16, 2002 as well as
the additional information received on May 26, 2003; July 18, 2003; August 29, 2003; and May 18, 2004;
we are forwarding herewith a renewed and modified Permit No. WQ0021828, dated May 28, 2004, to the
Orange Water and Sewer Authority (OWASA) for the subject residuals digestion facility and Class A EQ
residuals product distributiorJland application program.
This permit shall be effective from the date of issuance until April 30, 2009 and shall be subject
to the conditions and limitations as specified therein. Make note of this permit's expiration date and the
fact that a permit renewal application is due to the Division of Water Quality (Division) no later than six
months prior to that date (i.e., see Condition V1. 7.), as the Division does not send reminders to apply for
permit renewal.
Remember to take the time to review this permit thoroughly. Pay particular attention to the
monitoring requirements in this permit. Please be aware that failure to establish an adequate system for
collecting, maintaining, and submitting the required operational information will result in future
compliance problems. Of special interest to you may be the following:
♦ Condition I. 1. requires the Permittee to develop and implement an educational program
regarding the Class A EQ residuals product distribution/land application program as well as a
mechanism for resolving inquiries from the public about the program components within 180
calendar days of this permit's issuance.
Be aware that 40 CFR Part 503 does not allow the use of a geometric mean to demonstrate
compliance with the fecal coliform density part of the Class A pathogen reduction
requirement. For more information about complying with the Class A pathogen reduction
requirements as stipulated under the federal regulation, please refer to the guidance document
entitled "Control of Pathogens and Vector Attraction in Sewage Sludge (EPA/625/R-
92/013)" that was published by the United States Environmental Protection Agency in 1999.

♦ It is the Division's understanding that the Permittee will be operating the Class A EQ
residuals product distribution/land application program in conjunction with the Class B
residuals land application program that is already in existence. The Division urges the
Permittee to take extreme care to ensure that the two products are managed separately and in
a manner that is consistent with the requirements of the product's respective permits. Any
Class A EQ residuals product that is mixed or comes into contact with Class B residuals shall
be treated as Class B residuals unless it is reintroduced limo the digestion facility for treatment
and demonstrated to the satisfaction of the Division that it meets the requirements of this
permit.
If any parts, requirements, and/or limitations contained in this permit are unacceptable, you have
the right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request shall be in the from of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes and filed with the Office of Administrative Hearings at 6714 Mail Service
Center, Raleigh, North Carolina 27699-6714. Unless such demands are made, this permit shall be final
and binding.
If you need any additional information concerning this matter, please contact Mr. J.R. Joshi by
telephone at [phone], extension 363, or via e-mail at Jaya [e-mail].

b. Any failure of the residuals digestion facility or Class A EQ residuals product
distribution/land application program resulting in a release of material to receiving
waters.
c. Any time that self-monitoring information indicates that the residuals digestion facility or
Class A EQ residuals product distribution/land application program has gone out of
compliance with the conditions and limitations of this permit or the parameters on which
the system was designed.
d. Any process unit failure, due to known or unknown reasons, that render the residuals

IV. GROUNDWATER REQUIREMENTS
1. Land Application Site Requirements:
a. No residuals shall be land applied to any Iand application site when the vertical
separation between the depth of residuals distribution/land application and the water table
is less than three feet. The actual water table depth shall be verified by soil borings
within 24 hours prior to any residuals distribution/land application event. The number of
borings advanced shall be sufficient to characterize water table conditions across the site
adequately. Any open borings shall be properly filled with native soil, prior to the
residuals distribution/land application event, to decrease the chance of any residuals
contaminating the groundwater.
2. Applicable Boundaries:
a. The COMPLIANCE BOUNDARY for Class A EQ residuals product distribution/land
application programs is specified by regulations in 15A NCAC 2L (i.e., "Groundwater
Classifications and Standards"). The Compliance Boundary for each land application
site is established at either 250 feet from the land application area or 50 feet within the
property boundary, whichever is closest to the land application area. An exceedance of
Groundwater Quality Standards at or beyond the Compliance Boundary is subject to
immediate remediation action according to 15A NCAC 2L .0106 (d)(2).
b. The REVIEW BOUNDARY shall be established around each land application site
midway between the Compliance Boundary and the perimeter of the land application
area. Any exceedance of Groundwater Quality Standards at the Review Boundary shall
require action in accordance with 15A NCAC 2L .0106 (d)(2).
Other Requirements.
a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
V. INSPECTIONS
The Permittee or his designee shall inspect the residuals digestion facility as well as the
facilities related to the Class A EQ residuals product distribution/land application program to
prevent malfunctions and deterioration, operator errors and discharges which may cause or
lead to the release of wastes to the environment, a threat to human health, or a nuisance. The
Permittee shall maintain an inspection log or summary including at least the date and time of
inspection, observations made, and any maintenance, repairs, or corrective actions taken by
the Permittee. This log of inspections shall be maintained by the Permittee for a period of
five years from the date of the inspection and shall be made available to the Division or other
permitting authority, upon request.
2. Any duly authorized officer, employee, or representative of the Division may, upon
presentation of credentials, enter and inspect any property, premises, or place on or related to
the residuals digestion facility or CIass A EQ residuals product distribution/Iand application
program at any reasonable time for the purpose of determining compliance with this permit;
may inspect or copy any records that must be kept under the terms and conditions of this
permit; and may obtain samples of groundwater, surface water, or leachate.
