Subject: Letter of Permission to Modify
Monitoring Requirements Permit No. WQ0001204

Land Application of Nitrogen -Enriched Groundwater
Hertford County
Dear Mr. Hall:
In accordance with a modification request on November 30, 1998 and
condition III,(4),(d) of the subject permit; we are sending this letter as
permission to reduce the amount of groundwater monitoring used in the land
application program. This modification reduces the approved monitoring to a
field test every 25 trucks(125,000 gallons) and a laboratory test every 100
trucks(500,000 gallons). However, in the event four consecutive field tests
and one laboratory test vary more than 20%, the original monitoring shall
resume. When the requirements of condition 111,(4),(d) are again met, the
reduced monitoring may begin again. This letter changes condition
I11,(4),(a&b) only with respect to frequency, not parameters. All other
conditions shall remain in-place for permit no. WQ0001204.
This Letter of Permission shall be effective from the date of issuance
until March 31, 2002, the same as the subject permit"
If you have any questions in regard to this matter, please contact Mr.
Al Hodge, Environmental Engineer, in the Washington Regional Office, at
