Dear Mr. McAtee:
In accordance with your permit renewal application package received on December 31, 2001 as
well as the additional information received on April 2, 2002; we are forwarding herewith a renewed Permit
No. WQ0O05458 dated May 9, 2002, to BASF Corporation for the subject residuals land application
program.
This permit shall be effective from the date of issuance until April 30, 2007; shall void Permit No.
WQ0005458 issued on June 11, 2001; 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 VI.
7.), as the Division does not send reminders to apply for permit renewal.
This permit approves the continued operation of the residuals land application program for another
five-year cycle. As always, remember to take the time to review this pennit thoroughly, as some of the
conditions contained therein may have been added, changed, or deleted since the last issuance. Pay
particular attention to the monitoring requirements in this permit. Failure to establish an adequate system
for collecting and maintaining the required operational information will result in future compliance
problems.
Please note Attachment A footnotes with regard to addressing the possibility of high Nickel
concentrations in the residuals until a synthesis of Vitamin C process is shutdown. In a response to
questions about previous high concentrations, the Permittee made note that they did not believe grab
samples of the residuals to be accurate representation of the residuals. The Division strongly concurs. All
samples should be conducted so that they are representative of the material being sampled. Please note
Condition III. 3 that indicates a representative sample of the residuals shall be conducted. The Permittee
shall be responsible for assuring that sampling is conducted so that it is representative of the material.

on all land application sites onto which residuals are land applied to ensure optimum yield for
the crops specified in Condititna 11. 13. The agronomist shalt --provide information on the pH
best suited for the specified crop and the soil type.
10. Should any of the residuals generated by the residuals source -generating facilities listed in the
most recently -certified Attachment A of this permit contain a high salt content (i.e., high
sodium adsorption ratio (SAR) of five or higher), the exchangeable sodium percentage (ESP)
or other method as approved by the Division, using the results from the annual soils analysis
as required by this permit, shall be monitored on all of the land application sites. The local
Cooperative Extension Office, the Department of Agriculture and Consumer Services, the
Natural Resource Conservation Service, a North Carolina -licensed Soil Scientist, or other
agronomist shall review the results and make recommendations regarding soil amendments
(e.g., gypsum, etc.) or other ameliorative mechanism for maintaining the integrity of the site in
terms of suitability for land application of residuals and maintaining conditions conducive to
crop growth. The Permittee shall implement such recommendations accordingly and shall
maintain written records of each monitoring event that includes details of the sites covered
and rate of soil amendment application.
11. Prior to land applying residuals to any land application site that has previously received or is
intended to receive animal waste (e.g., poultry litter, etc.) or other source of nutrients (e.g.,
fertilizer, etc.) in the future, the Permittee shall obtain information pertaining to the volume
and analysis of the applied waste/nutrients from the landowner and/or lessee/operator of the
site. The Permittee shall be responsible for verifying the volume of residuals that may be land
applied to the site such that the plant available nitrogen (PAN) loading rate for the specified
crop (i.e., see Condition 11. 13.) shall not be exceeded by all of the sources of PAN applied.
Should the maximum PAN loading rate be met or exceeded, then no additional residuals shall
be land applied to the site.
_ 12. A suitable vegetative cover, as listed in Condition H. 13., shall be maintained on land
application sites onto which residuals are land applied in accordance with the crop
management plan outlined by the local Cooperative Extension Office, the Department of
Agriculture and Consumer Services, the Natural Resource Conservation Service, or other
agronomist and as approved by the Division.

13. Residuals and other sources of PAN shall be land applied to all land application sites at
agronomic rates in accordance with the crop management plan outlined by the local
Cooperative Extension Office, the North Carolina Department of Agriculture and Consumer
Services, the Natural Resource Conservation Service, or other agronomist. Under no
circumstances shall the following PAN loading rates land applied to any site exceed the
following for the specified crops:

The Permittee shall apply for and receive a modification of this permit before land applying
residuals on any land application site that is to be established in a crop other than those listed
above. A maximum PAN loading rate for the desired crop shall be approved with the permit
modification.
If the land application sites are to be overseeded (e.g., bermuda grass in the summer and rye
grass in the winter with BOTH crops to receive residuals), then the second crop shall receive
an application of PAN at a rate of no greater than 50 pounds per acre per year. This practice
shall be allowed as long as the second crop is to be harvested. If the second crop is to be
planted for erosion control only and is to be tilled into the soil, then no residuals shall be land
applied to these sites because the PAN will essentially be returned to the soil.
Residuals shall not be land applied at rates greater than agronomic rates, unless authorized by
the Division.
14. Animals shall not be grazed on any land application site for 30 days after any residuals land
application event. Sites that are to be used for grazing shall have fencing that will be used to
prevent access after each event.
15. Food crops, feed crops, and fiber crops that do not come in contact with the residuals shall not
be harvested for 30 days after any residuals land application event.
16. Food crops with harvested parts that touch the residual/soil mixture and are totally above the
land surface (e.g., tobacco, melons, cucumbers, squash., etc.) shall not be harvested for 14
months after any residuals land application event.

17. Food crops with harvested parts below the surface of the land (i.e., root crops such as
potatoes, carrots, radishes, etc.) shall not be harvested for 20 months after any residuals land
application event when the residuals remain on the Iand surface for_ four months or longer
prior to incorporation into the soil.
18. Food crops with harvested parts below the surface of the land shall not be harvested for 38
months after any residuals land application event when the residuals remain on the land
surface for less than four months prior to incorporation into the soil. -
19. Turf shall not be harvested for one year after any residuals land application event.
20. Adequate provisions shall be taken to prevent wind erosion and surface runoff from conveying
residuals from the land application sites onto adjacent properties or into any surface waters.
21. Adequate procedures shall be provided to prevent surface runoff from, carrying any land
applied or stored residuals into any surface waters.
22. Surface -applied residuals shall be plowed or disced within 24 hours after land application on
land application sites with no cover crop established.
23. For land application sites that are prone to flooding or within the 100-year flood elevation,
residuals shall be land applied only during periods of dry weather. The residuals shall be
incorporated into the soil within 24 hours after land application.
24. Residuals shall not be land applied during inclement weather or until 24 hours following a
rainfall event of 0.5-inch or greater in 24 hours. Any emergency residuals land application
measures shall first be approved in writing by the Division.
25. Residuals shall not be land applied to any land application site that is flooded, frozen, or
snow-covered.
26. Appropriate measures shall be taken to control public access to the land application sites
during active site use and for the 12-month period following the last residuals land application
event. Such controls may include the posting of signs indicating the activities being
conducted at each site.
III. MONITORING AND REPORTING RE IRREMENTS
1. Any monitoring (i.e., including groundwater, surface water, residuals, soil, or plant tissue
analyses) deemed necessary by the Division to ensure protection of the environment shall be
established, and an acceptable sampling and reporting schedule shall be followed.

2. Residuals generated by each residuals source -generating facility listed in the most -recently -
certified Attachment A of this permit shall be analyzed to demonstrate that they are non-

ignitability, and reactivity analysis as well as a Toxicity Characteristics Leaching Procedure
(TCLP) analysis shall be conducted on residuals generated by each residuals source -
generating facility listed in the most recently -certified Attachment A of this permit. The
analyses shall be performed at the frequency specified in the most recently -certified
Attachment A of this permit, and the results shall be maintained on file by the Permittee for a
minimum of five years. If residuals generated by a particular residuals source -generating
facility are land applied at a frequency less than that which is specified in the most recently -
certified Attachment A of this permit, the analyses shall be required for each residuals land
application event. Only residuals that are generated by the residuals source -generating
facilities that are identified as being exempt from this condition in the most recently -certified

After the residuals generated by a particular residuals source -generating facility have been
monitored for two years at the frequency specified in the most recently -certified Attachment A
of this permit, the Permittee may submit a request to the Division for a permit modification to
reduce the frequency of this monitoring requirement. In no case, however, shall the frequency
of this monitoring be less than once per year when a residuals land application event of
residuals generated by the residuals source -generating facility occurs during that year.
4, Residuals generated by each residuals source -generating facility listed in the most recently -
certified Attachment A of this permit shall be monitored for compliance with Condition I. 9.
The monitoring shall be performed at the frequency specified in the most recently -certified
Attachment A of this permit, and data to verify pathogen and vector attraction reduction of the
residuals shall be maintained on file by the Permittee for a minimum of five years. The
required data shall be specific to the stabilization process utilized, but also shall be sufficient
to demonstrate clear compliance with the Class A pathogen reduction requirements in 40 CFR
Part 503.32(a) or the Class B pathogen reduction requirements and site restrictions in 40 CFR
Part 503.32(b) as well as one of vector attraction reduction requirements in 40 CFR Part
503.33. In addition, the Environmental Protection Agency (EPA) certification statements
concerning compliance with pathogen reduction requirements, vector attraction reduction
requirements, and management practices shall be completed quarterly by the proper authority
or authorities, if more than one is involved (i.e., either the person who prepares the residuals,
the person who derives the material, or the person who applies the residuals). Only residuals
that are generated by the residuals source -generating facilities that are identified as being
exempt from Condition 1. 7. in the most recently -certified Attachment A of this permit shall
not be required to comply with this monitoring requirement.

5. Laboratory analyses as required by Condition 111. 2., Condition III. 3., and Condition III. 4.

case more than 24 hours or on the next working day following the occurrence or first
knowledge of the occurrence of any of the following:
a. Any occurrence with the residuals land application program that results in the land
application of significant amounts of residuals that are abnormal in quantity or
characteristic.
b. Any failure of the residuals land application program resulting in a release of material to
receiving waters.
c. Any time that self -monitoring information indicates that the residuals land application
program has gone out of compliance with the conditions and limitations of this permit or
the parameters on which the program system was designed.
d. Any process unit failure, due to known or unknown reasons, that render the residuals land
application program incapable of adequate residuals treatment.
e. Any spillage or discharge from a vehicle or piping system transporting residuals to the
application site.
M Persons reporting such occurrences by telephone shall also file a written report in letter form
within five days following first knowledge of the occurrence. This report shall outline the
actions taken or proposed to be taken to ensure that the problem does not recur:
IV. GROUNDWATER REQUIREMENTS
1. Land Application Site Re uirements:
a. Each land application site identified with a GW-A in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
greater than three feet below the land surface. Residuals land application events may
occur on these sites throughout the year.

b. Each land application site identified with a GW-B in the most recently -certified
Attachment B of this permit is dominated by soils with a mean seasonal high water table
between one and three feet below, the land surface. ResLdual land application events on
these sites shall be prohibited from December through March, inclusive. No residuals
shall be land applied to these sites when the vertical separation between the depth of
residuals land application and the water table is less than three feet. The actual water
table depth for seasonally -restricted soils shall be verified by soil borings within 24 hours
prior to any residuals land application event that occurs from April through November,
inclusive. The number of borings advanced shall be sufficient to characterize water table
conditions across the land application site adequately. Any open borings shall be properly
filled with native soil, prior to the residuals land application event, to decrease the chance
of any residuals contaminating the groundwater.
2. Sampling Criteria:
a. Nomenclature for monitoring wells shall be referenced as follows:

b. Monitor wells MW-1, MW-4, MW-5, MW-6, MW-7, and MW-8, shall be sampled every
March, July, and November for the parameters listed below. Prior to sampling the
parameters the measurement of water levels must be taken. The depth to water in each
well shall be measured from the surveyed point on the top of the casing. The measuring
points (top of well casing) of all monitoring wells shall be relative to a common datum.
Nitrate (NO3-N) pH
Chloride Total Dissolved Solids (TDS)
Total Ammonia Nitrogen (NH3-N) Total Organic Carbon (TOC)
Water Level Sodium
Zinc Chromium
Total Phosphorous
Methanol - sampled in November only
Acetone- sampled in November only
Isoprophyl Alcohol- sampled in November only
Volatile Organic Compounds - In November only using one of the following:
(A) Standard Method 6230D, PQL at 0.5 ug/L or less
(B) Standard Method 6210D, PQL at 0.5 ug/L or less
(C) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
(D) EPA Method 8260, Low Concentration, PQL at 0.5 ug/L or less
(E) Another method with prior approval by the Groundwater Section Chief

Any of the referenced methods used for VOCs must at a minimum include all the
constituents listed in Table VIII of Standard Method 6230D. Any method used must
provided a PQL at 0.5 ug/L or less which must be supported by laboratory proficiency
studies as required by the DWQ Laboratory Certification &nit. Any constituents detected
above the MDL but below the PQL at 0.5 ug/L must be qualified (estimated) and reported.
c. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring
well, additional sampling and analysis must be conducted to identify the individual
constituents comprising this TOC concentration. If the TOC concentration as measured in
the background monitor well exceeds 10 mg/l, this concentration will be taken to
represent the naturally occurring TOC concentration. Any exceedances of this naturally
occurring TOC concentration in the downgradient wells shall be subject to the additional
sampling and analysis as described above.
d. Any laboratory selected to analyze parameters must be Division of Water Quality (DWQ)
certified for those parameters required.
Applicable Boundary Requirements:
a. All reports and documenation (GW-59) shall be mailed to the following address:
Groundwater Section
Permits and Compliance Unit
1636 Mail Service Center
Raleigh, NC 27699-1636
Updated blank forms (GW-59) may be downloaded from the Groundwater Section's
website at http://gw.ehnr.state.nc.us/ or requested from the address mentioned above.
b. The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Groundwater Section (address
listed above), on or before the last working day of the month following the sampling
month. The data of all groundwater sampling analyses required by the permit conditions
must be reported using the most recent GW-59 form along with attached copies of the
laboratory analyses.
4. Applicable Boundary Re uirements:
c. The COMPLIANCE BOUNDARY for residuals 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 residuals land application area or 50 feet within the property boundary, whichever is
closest to the residuals Iand application area. An exceedance of Groundwater Quality
Standards at or beyond the Compliance Boundary is subject to immediate retnediation
action according to 15A NCAC 2L .0106 (d)(2).
d. The REVIEW BOUNDARY shall be established around each land application site
midway between the Compliance Boundary and the perimeter of the residuals land
application area. Any exceedance of Groundwater Quality Standards at the Review
Boundary shall require action in accordance with I5A NCAC 2L .0106 (d)(2).
Additional Requirements:
a. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
