Summary
Heater Utilities — Killian Crossroads W WTP (formerly Mid South Utilities) requires a NPDES
discharge permit to dispose of domestic wastewater to waters of the state. Killian Crossroads
W WTP's NPDES permit has expired and they have requested renewal of their permit. The
Division of Water Quality's NPDES Unit issues the permits for individually permitted facilities,
and determines the conditions that must be achieved prior to discharging wastewater. This face
sheet summarizes the rationale used to determine permit limits and conditions.
Heater Utilities owns and operates a 0.05 MGD wastewater treatment system in Catawba
County. The class II facility serves a residential area and consists of the following treatment
units:
• Influent surge tank w/ flow splitter box
• Bar screen
• Dual aeration basins with diffused air
Fact Sheet
MIMES Renewal
Page 1

• Dual secondary clarifiers
• Dual tertiary filters
• Diffused post aeration
• Tablet chlorination with contact chamber
• Tablet dechlorination
• Cascade post aeration
• Aerated sludge holding tank
• Stand-by power generator
Heater Utilities obtained ownership of the facility on or about July 1999. Prior to Heater
Utility's management, there were chronic compliance problems associated with the facility.
Under Heater Utilities operation, the facility has not been issued any NOVs or civil
assessments, indicating that compliance has improved.
This is a phased permit with a build out permitted flow of 0.075 MGD. According to the region,
this area is fairly undeveloped and the 0.075 MGD flow is justified.
Thus far in 2000, the facility has averaged 0.0228 MGD or 45.6% of the currently permitted flow
rate. There is one discharger (Cross Country Campground) approximately 0.7 miles upstream
of Killian Crossroads that also discharges to Reed Creek. It is recommended that Cross County
approach Heater Utilities for possible connection to the Killian Crossroads WWTP.
Residuals are removed as needed by Roberts Septic Service for disposal at the City of Newton
WWTP.
The limits imposed on the discharge are based on the management strategy for Lake Norman
dischargers (15-BOD/4-ammonia). Additional limitations include a limit for MBAS, oil &
grease, total residual chlorine, TSS, dissolved oxygen, and pH. Aside from the standard
boilerplate conditions the permit contained a condition requiring the facility to submit plans
and specifications for the expansion upon reaching 80% of the permitted flow.
Proposed Changes
It is recommended that in -stream fecal coliform monitoring continue to be required on a
monthly basis. Division policy for dischargers of 100% domestic wastewater is removal of in -
stream monitoring for fecal coliform and conductivity. The in -stream data indicated that the
fecal counts in the receiving stream average close to 200/100 MI. The difference between the
upstream and the downstream fecal counts is small. The data does not suggest that the
discharger is contributing fecal coliforms in the stream. Since fecal counts are averaging close
to the state standard it is recommended that the facility be required to continue in -stream fecal
monitoring and that the monitoring frequency be modified to monthly.
It is recommended that in -stream conductivity monitoring be deleted as a condition for the
permit. In -stream conductivity monitoring appeared normal, therefore it is recommended that
the conductivity monitoring be removed from the permit according to current division
procedure for 100% domestic dischargers.
Removal of in -stream TN and TP monitoring. The current permit only required the monitoring
through August 1998. Modeling staff indicated that there was no need to require additional TN
and TP monitoring in -stream. Therefore, TN and TP in -stream monitoring shall be removed
from the permit. The facility shall continue to monitor TN and TP in the effluent from the
facility.
The special condition requiring the facility submit plans and specifications for expansion upon
reaching 80% of the current 0.05MGD flow limit has been removed. The reason for this special
condition could not be established. It is the responsibility of the permittee to ensure that they

do not exceed the permitted flow. In the event that the flow limit is violated, the facility would
be subject to enforcement from the Division. There are other mechanisms and controls in place
to ensure that the facility has the proper treatment at a particular flow, it is not necessary to
place this special condition in the permit.
MBAS — the reasonable potential was conducted with available data from July 1999 through
September 2000. Data from prior to July 1999 reflects Mid South Utilities operation of the
facility, therefore, no data prior to this time was used in the reasonable potential analysis. The
reasonable potential analysis results indicated that there is no reasonable potential for the
discharge to cause a violation of the stream standard. Therefore, it is recommended that the
limit for MBAS be removed from the permit.
MBAS monitoring remains as a condition for the facility. The self -monitoring data indicated
that MBAS might be present in the effluent. Though there is not reasonable potential that the
discharge will cause a violation of the stream standard, the presents of MBAS should be
monitored.
Current Stream Conditions
The receiving stream is Lake Norman (Reed Creek). The discharge is at the mouth of Reed
Creek where it empties into Lake Norman. Lake Norman at the point of discharge is a class
WS-IV & B water in the Catawba River Basin. Lake Norman (Reed Creek) is not listed on the
state's 303(d) list and has been rated as 'supporting' its designated uses. DWQ sampled Lake
Norman in 1981, 1982, 1983, 1986, and 1992. In 1982,1986 and 1992 the lake received an
oligotrophic rating. According to the information presented in the basin plan and the use
support rating, water quality in the receiving water is generally good.
Instream Monitoring
No instream monitoring is currently required'.
No instream monitoring is recommended during this permit cycle.
Compliance Summary: (see Appendix B)
As noted above, under the ownership of Mid South Utilities Killian Crossroads had chronic
compliance problems. Since ownership was transferred to Heater Utilities compliance at the
facility is improved. Under Heater Utilities operation there are no documented violations of
permit limits.
Toxicity Testing
Current Requirement: None.
Recommended Requirement: None recommended.

4. Alternative Analysis Evaluation
a. Spray Irrigation: Insufficient area.
b. Connect to regional sewer system: There is currently no regional sewer system
available to service this area. Catawba County is considering serving this area
with sewer from either a WWTP the county will own and operate or sewer service
will be extended from the City of Newton to service this area.
C. Subsurface: Insufficient area.
d. Other disposal options: None that we are aware.
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, Heater Utilities (HU), has requested renewal of the subject Permit. There
have been no changes to the WWTP or the Permit since the Permit was last reissued. HU has,
however, made many safety and operational improvements to the WWTP such as the repairing of
deteriorating tankage, pipes, and walk -ways that should improve overall operational flexibility.
Pending receipt, review, and approval of the WLA, it is recommended that the Permit be
renewed as requested.
