Nonpoint Source Pollution Management Act of 1983

Nonpoint Source Pollution Management Act of 1983 - Amends the Clean Water Act ("the Act") (also known as the Federal Water Pollution Control Act) to provide for a nonpoint source pollution management program.

Requires each State, by itself or in combination with other States and after notice and opportunity for public comment, to submit a proposed nonpoint source pollution management program to the Administrator of the Environmental Protection Agency within 18 months after the enactment of the Clean Water Act Amendments of 1983.

Requires that such proposed State program: (1) identify waters within State boundaries which, without additional action to control nonpoint sources of pollution, cannot be reasonably expected to attain or maintain applicable water quality standards or the goals and requirements of the Act; (2) designate categories or subcategories of nonpoint sources of pollution or, where appropriate, particular nonpoint sources, that contribute significant pollution loadings to such identified waters; (3) identify best management practices which will be undertaken to reduce pollutant loadings resulting from each designated category, subcategory, or particular nonpoint source; (4) identify programs to achieve implementation of such best management practices; (5) include a schedule containing annual milestones for utilization of program implementation methods and implementation of best management practices at the earliest practicable date; (6) include a statement by the State attorney general, or attorney for the State water pollution control agency, that State laws provide adequate authority to carry out the program, or a schedule and commitment by the State to seek such authorities as expeditiously as practicable; and (7) include an indentification of Federal financial assistance programs and Federal development projects for which the State will review individual assistance applications or development projects for their effect on water quality, pursuant to specified procedures, to determine whether such applications or projects would be consistent with and further the purposes and objectives of the program.

Allows the State, in developing such program to rely upon specified information and utilize appropriate elements of waste treatment management plans. Allows the State, in developing and implementing such program, to make use of local agencies or organizations.

Sets forth procedures and deadlines for revisions and approval or disapproval by the Administrator of such proposed or revised State programs.

Directs the Administrator to report to the Congress on actions taken with regard to any State which fails to submit a program which meets specified requirements.

Provides that two-thirds of the funds appropriated in any fiscal year for such grants shall be allotted among States according to a specified table of percentage allotments. Provides that one-third of such appropriations shall be made available to the Administrator who shall make grants in response to applications from States if the Administrator determines such grants are necessary and appropriate to assist such States in: (1) controlling particularly difficult or serious nonpoint source pollution problems, including those resulting from mining; (2) implementing innovative methods or practices for controlling nonpoint sources of pollution, including both regulatory or nonregulatory programs where appropriate; (3) controlling interstate nonpoint sources pollution problems; or (4) providing financial assistance, limited to a specified amount, for approved management program implementation by an Indian tribe within the reservation.

Directs the Administrator to transmit to the Office of Management and Budget and the appropriate Federal departments and agencies a list of those assistance programs and development projects identified by States for which individual assistance applications and projects will be reviewed. Requires each Federal department and agency, within 60 days after receiving such notification, to: (1) modify existing regulations to allow States to conduct such review; and (2) accommodate the concerns of the State regarding the consistency of such applications or projects with the State program.
