Act 167

Pennsylvania’s Storm Water Management Act (Act 167) was enacted in 1978, in response to the impacts of accelerated stormwater runoff resulting from land development in the state. The Act requires counties to prepare and adopt watershed based stormwater management plans—and requires municipalities to adopt and implement ordinances to regulate development consistent with these plans. The DEP provides technical, administrative and financial assistance to counties in preparing Stormwater Management Plans and pays for 75% of the costs counties incur in preparing plans. DEP also approves reimbursements to municipalities for 75% of the allowable costs of preparing plans and for enacting, administering, and implementing stormwater ordinances.
