The following were among actions taken at Tuesday's meeting of the Prince George's County Council. For more information, call 952-3182.

RECYCLING -- The County Council, in a unanimous vote, adopted an ambitious mandatory recycling plan that is expected to exceed the state's mandate to reduce solid waste disposal by 20 percent by 1994.

Council members said the county's recycling program, which is currently voluntary, is expected to reduce solid waste disposal by 35 percent by 1999.

The county has until July 1 to adopt a recycling plan in accordance with Maryland's recycling law. A variety of recycling programs, incuding composting leaves and garden waste and collecting aluminum cans and bottles, will be used in the attempt to reduce the county's estimated 2,400 tons of daily trash.

HOUSING -- The council voted to hold public hearings on proposed legislation designed to encourage building of moderately-priced housing in the county for families whose annual income is under $40,000 a year.

One piece of legislation would set up eligibiity and compliance requirements for developers and would establish an advisory board to oversee the housing initiatives. Another proposes allowing developers to cover 10 percent of planned developments with town houses -- thus allowing more houses on a property than current zoning permits -- in exchange for building moderately-priced housing. Another proposes establishing income eligibility requirements for county residents.

The council also voted to hold public hearings on legislation that would create two programs to help moderate income-eligible county residents with one-time home purchasing expenditures including closing costs.

CHARTER -- The council gave preliminary approval to an amendment to the Prince George's County Charter that would require the council to hold an election if a council seat is vacated more than 90 days before a primary or general election.

Council members, criticized by residents for the method of choosing a successor to James M. Herl, who resigned while under indictment on drug charges, said they wanted to let voters chose any new members to the council through an election.
