Dear Ms. Gore:
Enclosed are two (2) copies of the revised PGW IUP (IWP001). Two modifications were made
to the permit as shown in the IUP History on the second page of the permit. Please note that a
certified copy of the permit was mailed to PGW on January 16, 2019
One modification was an increase in the annual average flow from 0.135 mgd to 0.150 mgd.
The other was a change in the IUP expiration date from 3/6/20 to 3/6/21.
The revisions will take effect January 20, 2019.

Discharge restrictions are set based on expected flow from plant production

STMP.
1

IUP Synopsis
RATIONALE#2(Rationale Specifics for Limitations):
The following rationale was used for developing IUP Limits.
1 Parameter Rationale
Flow Per IU request(peak instantaneous flow is based on limit
of receiving Candlewycke Punt. Station capacity).
pH Per WWTP NPDES Permit. lU's flow is significant and
would require additional buffering at WWTP if outside 6
to 9 SU's.
Grit Based on WWTP grit removal system capacity,IU
monthly average discharge of 0.12 mgd,particle size>
0.2 mm,and specific gravity(S.G.)of glass 2.65.
Limitation also needed to protect downstream equipment,
and is therefore limited to normal domestic sewage
characteristic.
Oil and Grease Per YVSA SUO (Section 2.3 Local Limits)
RATIONALE#3 (Categorical Industrial Limits,with no Over Allocation Situation):
Check if Combined Wastestream Formula(CWF) or other categorical limits
