Wren Thedford:
I am requesting the renewal of NPDES Permit No.NC0028711 to continue to operate
the waste water treatment plant(WWTP)at Berryhill School. No structural changes have
been made to the WWTP since the current permit was issued. In addition to the permit
renewal,I am also requesting the removal of monitoring and reporting of dissolved oxygen
and temperature from the upstream and downstream effluent location from the permit. The
area we are monitoring from is beginning to be developed and we will likely need to relocate
to a new area. The change in location will push us further away from the effluent discharge
location.
