Facility is renewing at existing flow with no change in wastewater characteristics. Fecal limit
should be changed to 200/100 nil. A modification request was made for the deletion of the residual
chlorine test. There is no basis to agree to this request.
Summer and winter limits for NH3 (based on toxicity) should be 1 mg/1 and 17.1 mg/1
respectively. A choice will be given between these new limits or a toxicity test (P/F @ 90%). .

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Has the facility demonstrated the ability to meet the proposed new limits with existing treatment
facilities? Yes v' No
If no, which parameters cannot be met?
Would a "phasing in" of the new limits be appropriate? Yes _ No �
If yes, please provide a schedule (and basis for that schedule) with the regional
office recommendations:
If no, why not?

Subject: Waiver of Effluent Monitoring Requirements on Daily
Chlorine Residual
Sirs,
As the new ORC for the Dunn's Mobile home park as of 11-
18-1991 I have been requested to type a letter to you on
behave of the owner Mrs. Dunn.
In meeting with Mrs. Dunn on 11-18-1991 I was requested
to do the testing and monitoring for the facilites in her
recent advisement that the present ORC would not be working
for her as of preveous dates.
Mrs. Dunn requested that I do a weekly monitoring as had
been done since the issued permitt in 1987. I advised Mrs.
Dunn that according to the present permitt that a daily
residual Chlorine test was required. Mrs. Dunn advised me
that according to her records only weekly readings where
being done and that she could not afford to pay for daily
monitoring from the ORC.
The present permitt is due for renewall on August 1992
and in light of this and the following factors We request a
waiver on Daily Chlorine Residual Readings in the present and
future permitts.
1) Mrs. Dunn's Grandson puts Chlorine in Sanurail Chlorinator
every two to three days as needed (with the low flow and
present chlorinator the chlorine should last seven days
with no problems.)
2) On of the residents in the park checks the plant daily and
also repairs equipment when needed.
3) If Mrs. Dunn who is 70 years old,cannot drive,has to pay
for daily monitoring she will have to close the facilities
therefore putting 12 (Twelve) families out of a place to
live.
Mrs. Evelyn Du (Owner)
Ar of E. Allre (ORC)
P.S. If a copy of the present permitt and any matters dealing
with the facility could be sent to the ORC the facility would
be better served.
