will convert it to a small preaeration tank. We have told him that he
can do that since the grease trap was useless and unnecessary. Call if

ATC SUMMARY Crown Mobile Home Park
South of Groometown, NC
ATC No. 05525SA01
Hickory Creek, Class WS-IV
Cape Fear River Basin, 030608
Guilford County
SCOPE
The scope of the project includes the installation of one 16,000 gallon equalization tank and
associated aeration equipment and sludge pumps.
RECOMMENDATIONS
1. Approve addition of 16,000 gallon equalization tank and all associated
aeration equipment, pumps and piping.
REVIEW SUMMARY
Executive Summary
The subject facility's existing permit was issued on July 23, 2001. The treatment works currently
consist of:
•Bar screen
•Grit and grease tank
-Aeration tanks in series
*Clarifiers in parallel
-Tablet chlorination
•Reaeration tank with diffused air
-Aerated sludge digester
The Winston-Salem Regional Office reports that the facility has experienced problems with
hydraulic surges, which then cause solids washouts. This has led to the several violations of
permit limits. To assist with compliance and to alleviate this problem of surging, the installation of
the 16,000 gallon equalization tank is recommended.

Equalization tank
Number of tanks: one
Capacity: 16,000 gallons
Additional features: Aeration to be provided by diffusers (air source is existing and has sufficient
capacity to support the new diffusers)
Sludge Pumps
Number of pumps: two
Pump type: 0.4 hp submersible pumps
Pump capacity: 40 gpm at 13-14 feet
Review Notes:
According to Steve Mauney of the Winston-Salem Regional Office (WSRO), the existing grease trap
has not been functioning for some time and so will be converted into a small preaeration tank. The
WSRO does not feel that a grease trap is necessary for this system. The grease trap will be
bypassed while the work on it is performed. Once the work is complete, wastewater will now to it
by gravity.
The proposed equalization tank provides more than the required 25% storage and seems to be
needed at this site due to the flow surges experienced at the plant. Hopefully, the installation of
equalization will enable the Permittee to achieve a more consistent level of treatment.
Recommendations
I recommend that the Authorization to Construct be issued for the installation of a 16,000 gallon
equalization tank and the conversion of the existing grease trap to a small preaeration tank.

Subject: Crown Mobile Home Park-Narrative
Project Number: A25801.00
Date: March 4, 2003
Many of the ongoing improvements at the Crown Mobile Home Park are considered to be
maintenance items and are being handled under the existing permit. This is based on discussions
with Steve Mauney of the Winston-Salem Regional Office. The narrative below is for items to be
done under the requested Authorization to Construct Pennit.
Project Narrative: Construct one 16,000 gallon equalization tank which is to be located
upstream of the existing grease trap. The equalization tank is to be aerated by diffusers and air
from the existing blowers. Piping for return sludge to pumped to the equalization basin shall be
added. The basin shall be furnished with two 0.4-Horsepower submersible pumps which are rated
for 40-GPM at 13-14 Feet. A gravity bypass shall be provided to the grease trap and bypassing
the grease trap. (As ongoing maintenance, the grease trap is being cleaned and aeration is being
added).
1 hope this is helpful. Please call me if you have any questions.

Application for Authorization to Construct
MacConnell &Associates, P.C. Project No.: A25801.00
Dear Mr. Goodrich:
On behalf of the Crown Mobile Home Park, we are pleased to submit an application package for an Authorization
to Construct Permit (ATC) with supporting documentation for the Crown Mobile Home WWTP. Please find
enclosed the following documents:
1. Three sets of Detailed Plans and Specifications (8'/2"x I I"format).
2. Two sets of design calculations.
3. Two sets of Flow Schematic 0/2"x I I"format).
4. A Construction Sequence Plan is not provided. Temporary by-pass piping will be provided during
installation of equalization basin.
5. Special Order By Consent Application with cover letter being sent concurrently to Mr. Dave
Goodrich.
This application addresses the permit limitations and conditions for this facility. The ATC is needed so that an
equalization basin and appurtenances can be permitted and constructed to correct the violations at the facility.
As always, we thank you for your assistance and quick response to this application. Please call me or Daniel
Vallero, at(919)467-1239, if you should have any questions, comments, and/or require additional information.
