Toxic Cleanup Equity and Acceleration Act of 1993

Toxic Cleanup Equity and Acceleration Act of 1993 - Amends the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) to absolve municipalities or other persons of liability (other than to the President) for claims of contribution or other response costs for the generation, transportation, or arrangement for the transportation, treatment, or disposal of municipal solid waste or sewage sludge.

Authorizes eligible persons (defined as persons against whom administrative or judicial actions are brought, or to whom notice is given of potential liability, for activities involving municipal solid waste or sewage sludge) to settle their liability with the President.

Requires final settlements to: (1) allocate to all activities for the management of municipal solid waste or sewage sludge a combined maximum of four percent of total response costs for the facility; (2) require eligible persons to pay only equitable shares of the maximum percentage; (3) limit payments based on inability to pay, litigative risks, and other equitable factors; (4) permit in-kind services with regard to response actions in lieu of cash contributions; (5) limit a publicly owned treatment works' payments if it has promoted the reuse of sewage sludge through land application; and (6) be reached even if a person is liable under other CERCLA provisions.

Authorizes the President to provide a covenant not to sue to persons who have entered into settlements. Absolves such persons of liability for contributions or other response costs for matters addressed in settlements. Reduces others' potential liability by the amount of a settlement, but bars discharging potentially responsible parties unless the settlement so provides.

Applies settlement provisions to municipalities or treatment works who engage in municipal solid waste or sewage sludge management activities occurring 36 months after this Act's enactment date only if the eligible person is a: (1) municipality and a qualified household hazardous waste collection program has been operating while such waste was collected and disposed; or (2) treatment works in compliance with the Federal Water Pollution Control Act.

Makes this Act retroactively effective to all actions commenced before this Act's effective date unless a final court judgment or approval of a settlement agreement has been granted.
