Dear Mr. Hall:
In accordance with a telephone request received today, we are forwarding herewith a corrected pages 5
and 6 of Permit No. WQ0012404, issued January 24, 2002, for the subject facility.
The following corrections have been made to the permit:

previously issued permit and a letter from the Division's Washington Regional Office dated.
February 24, 1999.
2. Condition III.4 (e): The sampling schedules that have been reduced in Conditions III.4
(a) and (b) may be increased with variation in future samples.
Please replace Pages 5 and 6 with the corrected Pages 5 and 6 into Permit No. WQ0012404, issued
January 24, 2002.
If you have any questions regarding this request, please do not hesitate to contact Sue Homewood at

2. Proper records shall be maintained by the Permittee tracking all application activities.
These records shall include, but are not necessarily limited to the following information:
a. date of nitrogen -enriched groundwater application,
b. location of nitrogen -enriched groundwater application (site, field, or zone #),
c. method of application,
d. weather conditions (sunny, cloudy, raining, etc.),
e, soil conditions,
f. type of crop or crops to be grown on land application site,
g. volume of nitrogen -enriched groundwater applied in gallons/acre,
h. continuous weekly, monthly, and year-to-date hydraulic (inches/acre) loadings for
each land application site,
i. annual totals, for each land application site, of plant available nitrogen (PAN) from
the nitrogen -enriched groundwater (lbs/acre), annual totals, for each land application
site, of phosphorus applied from all sources (lbs/acre), fertilizers applied (other than
from the nitrogen -enriched groundwater) (lbs. of PAN/acre), and annual totals, for
each field, of PAN from all sources
j. annual and cumulative pounds/acre of each heavy metal (which shall include, but not
be limited to cadmium, copper, lead, nickel, and zinc).
3. A representative annual soils analysis (Standard Soil Fertility Analysis) shall be
conducted on each land application site receiving nitrogen -enriched groundwater in the
respective calendar year and the results maintained on file by the Permittee for a
minimum of five years.
The Standard Soil Fertility Analysis shall include, but is not necessarily limited to, the
following parameters:
Acidity
Calcium
Copper
Magnesium
Base Saturation (by calculation)
Cation Exchange Capacity
Manganese Potassium
Percent Humic Matter Sodium
pH Zinc
Phosphorus
The Standard Soil Fertility Analysis (see above) and an analysis for the following
parameters shall be conducted once prior to permit renewal on soils from each land
application site which has received nitrogen -enriched groundwater during the permit
cycle.
Cadmium
Lead
Nickel
4. A nitrogen -enriched groundwater analysis program will be conducted from the date of
permit issuance by the Permittee and the results maintained on file by the Permittee for a
minimum of five years. The following program shall be conducted:
a. A nitrogen -enriched groundwater field analysis shall be completed every 25 trucks
(125,000 gallons). The analysis shall include the following parameters:
Ammonia -Nitrogen Phosphorus
Nitrate -Nitrite Nitrogen

b. A nitrogen -enriched groundwater laboratory analysis shall be completed every 100
trucks (500,000 gallons). The analysis shall include the following parameters:
Nitrate -Nitrite Nitrogen TKN
Ammonia -Nitrogen
c. A nitrogen -enriched groundwater laboratory analysis shall be completed every 90
days. The analysis shall include the following parameters:
Cadmium
Copper
Lead
pH
Nickel
Phosphorus
Zinc
Plant Available Nitrogen (by calculation)
Aluminum
Potassium
Sodium
Calcium Magnesium
d. Quarterly reports shall be submitted to the Water Quality Supervisor of the
Washington Regional Office and shall include all monitoring results within the
quarter. This report shall include but is not limited to the following:
1. The land application sites used for land application per quarter,
2. the amount of nitrogen -enriched groundwater applied per land application site,
3. the nitrogen applied per land application site,
4. the total amount of nitrogen -enriched groundwater recovered,
5. and the total amount of groundwater and nitrogen recovered per year.
e. In the event of four consecutive field tests and one laboratory test vary more than
20%, the monitoring schedules in conditions a and b above we revert back to the
previously permitted monitoring schedule until further notice by the Division.
5. A Toxicity Characteristics Leaching Procedure (TCLP) analysis of the recovered
groundwater in the storage basin shall be conducted by the Permittee once prior to permit
application submittal for reissuance. The TCLP analysis shall include the following
parameters (please note the regulatory level in mg/L in parentheses):
