BACM FeasibilityBACM FeasibilityEach jurisdiction determines which

measures are Best Available Control Measures (BACM) for their jurisdiciton based on feasible for implementation– 59 jurisdictions– Commit to implement– Justify why measure is not feasible

Local Government BACM Local Government BACM ProcessProcessAugust – September 2002:

– Local jurisdictions review measures and conduct evaluations to determine which measures may be potentially feasible to implement

– TPA boards (COGs) accept suggested list of measures

Next StepsNext StepsOctober – November 2002:

– Each implementing agency passes resolution describing the measures to be implemented

• Measure description• Legal authority for implementation• Funding for measures• Enforcement

Next Steps – Cont.Next Steps – Cont.October – November 2002:

– Each implementing agency describes reasons for rejecting any measures

• Technologically or economically infeasible• Otherwise unreasonable• Can the measure be strengthened
