Based on the above limit exceedance(s), you should re -sample your effluent and if the high
levels persist, then you should have your treatment system evaluated to determine if corrective
measures are needed to ensure the system functions as intended and meets the conditions of the

Within 30-days receipt of this letter, please submit a written response to this office detailing
the actions you will take to ensure your system is in full compliance with the permit

1 week prior to sampling:
Clean and clear discharge pipe:
1. If the pipe is covered, uncover it so that the effluent can flow freely and make enough room to
get a sample bottle underneath the pipe without touching it. The area can be leveled back off
after the annual sampling event.
2. Remove any debris from inside the pipe.
3. Remove any debris or vegetation surrounding the pipe that may be in the way of the contractor
pulling the sample.
Clean and clear the chlorinator: Do not inhale the chlorine fumes!! Always wear gloves when
handling chlorine and wastewater equipment.
4. Remove the chlorinator tubes.
5. Flush the chlorinator and tubes with water. If using a water hose DO NOT put the hose into the
chlorinator hold it above. You can use a nozzle to get a stronger flow if necessary. All of the
debris should be flushed out and should exit the discharge pipe.
6. Clean the tubes.
7. Place 2-3 chlorine pucks in each tube.
8. Place the tubes back into the chlorinator.
DO NOT SAMPLE immediately following a septic tank cleaning and or pump out. Let the system reset for
2-3 months before sampling.
Septic Tank Maintenance:
1. You are required to inspect the septic tank at least yearly to determine if solids must be removed
or if other maintenance is necessary. Septic tanks should be pumped out every five years or when
the solids level is found to be more than 1/3 of the liquid depth in the septic tank compartment,
whichever is greater. A pumping company can check the status periodically and determine when
pumping is required.
