I/A APPROVAL PROCESS HISTORYTitle 5 - 1995 Code (Oct 1994)
Nitrogen loading limitations (440 gpd/building acre)Nitrogen Sensitive Areas
Zone II of PWSIWPA of PWS
Areas served by on-site wells and on-site septicLimitations apply primarily to new construction or increase in flow but may be required for upgrades also under Maximum Feasible ComplianceCode did not go into full effect (March 31, 1995) until some I/As for N-reduction were approved.RSF established as standard (550 gpd/ac).
