The Prince George's County Council began considering a measure this week that would allocate up to $50 million in industrial bonds for the construction of pollution control devices at the Chalk Point electric plant near Eagle Harbor.

The legislation, which would not cost county taxpayers any money, say its backers, is designed to help the Potomac Electric Power Company resolve its air pollution problem in the southern part of the county.

The Chalk Point plant is among several Pepco generating facilities that have been criticized recently for the dark smoke billowing from their tall chimneys, according to Pepco spokesman John Grasser.

Grasser said that Pepco signed a consent agreement June 7, 1976 in Montgomery County Circuit Court agreeing to remedy the air pollution problem at the Chalk Point plant.

"We are planning to use the bonds to pay for air pollutions control devices that will act in tandem with devices we already have operating. These new devices will be positioned at the top of the chimneys and will remove additional particles from the exhaust," Grasser said.

"By putting the county name on the bonds, they (Pepco) will save millions of dollars, and this will mean that consumers will not have to pay higher rates on their electric bills," council member Francis B. Francois said.

Under state legislation adopted in 1972, Pepco would be able to purchase the pollution control equipment without paying the normal high rate of interest on the bonds, according to Francois.

Francois said Pepco would be able to repay the principal and interest on the bonds sold by the county at a lower "municipal interest rate" because Prince Geoge's County's name would appear on the bonds.

Officials said a similar agreement between Pepco and the county was worked out shortly after the legislation was passed. They said the county agreed to sell $25 million in industrial revenue bonds for air and water pollution control facilities at Chalk Point.

The new legislation, which was sent to the county fiscal planning committee this week, calls for construction and approved operation of the pollution control devices by 1981.

Pepco spokesman grasser said the Potomac River electric generating plant in Alexandria is also being refitted with air pollution control devices after a similar arrangement was worked out with Alexandria officials.

In other action, the county council sent to committee a bill that would ban "sexually stimulating literature" from display at county newstand, drug stores and variety shops.

The legislation, which is similar to that which has been considred in some Virginia jurisdictions, is aimed at preventing "minors from seeing naked bodies when they are buying candy bars," one proponent said.
