Operating Procedures for Septage Receival Stations
A. Clean-up Procedures for the septage receival stations
Upon entering the disposal stations the hauler shall discharge his load in such a manner that will
create minimal splash and spillage of liquid septage outside the bay. Each hauler will be responsible
for any spillage that occurs during the discharge of the load. Grating has been installed over the
sump to remove any excess trash from the septage load and the septage hauler will also be
responsible for removal of the trash and disposal into the containers provided.
1. Trash containers, rakes and shovels will be provided at each bay for disposal of all waste that is
captured by the grate. All trash should be cleaned up and any spillage of liquid waste should be
washed down, using the water hoses provided, into the sump after each discharge.(please do not
wash down any spills that are located outside the bays. Contact facility personal and they will
instruct you in the proper cleanup procedures for this type of spill.)
2. Progressive enforcement will be employed to maintain the cleanliness of the stations for health
and environmental safety of both the wastewater treatment plant personnel and the septage haulers
using the stations. Depending on the severity of the problem, enforcement steps shall be taken and
may include fines, clean-up costs and/or suspension of discharge privileges.
B. Grease discharges
1. Discharge of all viscous materials which may include grease and solids from grease traps, sludge
from oil/water separators and grit interceptors are prohibited by the Sewer Use Ordinance.
Analytical testing may be performed on each load discharged to the septage disposal station to
determine the concentrations of oil and grease in each septage load. Excessive grease loadings will
be investigated to validate the source and enforcement action will be undertaken if interference of
plant operations occurs. The enforcement action may include but is not limited to additional testing
at hauler’s expense, fines and/or suspension of discharge privileges.
C. Prohibited substances
1. Additional prohibited discharges include metals which have specified limits in the Sewer Use
Ordinance and the CMU-SP will be testing for these metals in each domestic septage discharge load.
Excessive concentrations will be investigated to validate the source and if interference or pass
through of the WWTP is detected enforcement action will be taken.
2. Any pump and haul load that contains hazardous materials, liquid petroleum fuels, waste oils,
corrosives, flammables, and petroleum derivative wastes is strictly prohibited.
3. The CMU reserves the right to refuse acceptance of any load or stop the discharge operation in
progress at any time.

and signed by the owner upon receipt of the automatic entry device.
6. To receive an automatic entry device and permission to discharge at the septage disposal station,
the pump and haul company must have received a North Carolina state permit, submitted all required
information to CMU, and submitted a $100.00 deposit with the application to discharge.
