Town of Holly Springs 201 Facility Plan Amendment
The NPDES Program has reviewed the subject document and offers the following comments:
• The population and flow estimates presented in the 201 Facility Plan Amendment are different than
the estimates included in the EIS for the Western Wake Regional Wastewater Management
Facilities. Population and flow estimates should agree in both documents.
• The flow estimate for the year 2005 is given as 1,728,945 gpd. This estimates seems high given that
the maximum average monthly flow for the first seven months of 2005 was 1.08 MGD and for the
year 2004 it was 1.01 MGD. The projections should be updated based on the most current
information.
• In a previous Environmental Assessment document submitted to the Division the Town of Holly
Springs indicated that the projected wastewater flow at full development was between 4.9 and 5.0
MGD. The 201 Facilities Plan Amendment now projects this flow to be 6.1 MGD, and the Western
Wake Regional Wastewater Treatment Facilities EIS projects this flow to be 8.28 MGD. A
discussion of the population and flow at full development should be included. Furthermore,
Progress Energy lands around the Shearon Harris Nuclear Plant appear to be included in the
planning area for the town. Since the development of the land around the nuclear plant is unlikely,
this area should be reevaluated.
• The speculative limits for 8 MGD included in the document apply only to the connection to the
effluent line from the Western Wake Regional Wastewater Management Facility. These speculative
effluent limits do not apply to a discharge to Utley Creek. The Division has informed Holly Springs
that in the event that the flows exceed the permitted flow before the Western Wake Regional
Facility is in place the Division will consider a SOC or appropriate permit conditions to allow the
continued discharge to Utley Creek.
