Subject: Non -Discharge Compliance inspection Report
Holly Ridge WWTF
Permit No. WQ0019907
Onslow county
A compliance inspection of the Holly Ridge Wastewater Treatment Facility -was conducted by
Stephanie Garrett and Joanne Steenhuis from the Wilmington Regional Office on July 1.7, 2015.
This Inspection was to verify that the facility Is operating In compliance with the conditions and
limitations specifled in Permit No. WQ0019907. Staff would like to thank Mr. Allen Rhue for his
time and assistance during the site evaluation.
The findings and comments noted during this Inspection are provided In the enclosed copy of
the "Compliance Inspection Report' for your review. Overall the facility is well operated and Is
deemed compliant. However, a primary Issue of concern is the flow rate which is nearing the
permitted limits of 260,626 gpd for the wastewater treatment plant and 240,179 gpd for the
disposal site. It is noted that the hydraulic capacity of the facility is limited by the disposal site
capacity (240,179 gpd), .
A review of the average flow records for 2014 (last calendar year) Indicates that the Influent
flow (at PP1001) was 232,782 gpd. This is 89% of the facility's hydraulic treatment capacity.
However, the hydraulic capacity of the facility is limited by the capadlty of the disposal site.
Therefore, In 2014, with a disposal capacity of 240,179 gpd and an influent flow of 232,782 gpd,
the facility reached 97% of -its hydraulic capacity. Records for the period from January through
May 2015 Indicate that the Influent daily flow was above the treatment permitted flow and
above the disposal capacity of the facility (flows ranged from 268,790 to 335.450 gpd), The
enclosed table summarizes the flow records and associated hydraullic capacity calculations.
Mr. Rhue stated that there are plans to divert some flow to the Summerhouse Plant, hopefully
by the end of the year. I acknowledge that our files include an Engineering Report
(Summerhouse Water Reclamation Facility Rehabilitation Project) prepared -by McKim & Creed
In 2012 and a copy of .the pernilt WQ0034007 for tho construction and operation upon

Therefore, to Comply with the requirements on iSA NCAC 02T.0118 (80-90 rule, enclosed
provide by August 25, 20i5 (1) an updated detailed compliance -schedule for co
activities required In each facility {molly Ridge and Summerhouse) to Implement the flop of f the

advised that if additional flow Is projected and as result the facility (WQ0019907) exceeds its$
disposal capacity, the facility will be placed on moratorium for additional taps (§ 143-215,67 c
