ANTI-SMOKING BILL -- The council introduced a bill by member William E. Hanna Jr. that would extend county smoking prohibitions to all parts of theaters, auditoriums, concert halls, factories and all retail stores.

In addition, it would prohibit smoking in the public areas of businesses, including lobbies, waiting rooms and bathrooms. Retail stores that employ fewer than eight people currently are exempt from antismoking laws.

In introducing the legislation, Hanna cited the U.S. Surgeon General's report that said nonsmokers are endangered by the smoke of others.

Smoking is already illegal in the county's health care facilities, elevators and large retail stores and in Montgomery County government buildings. It also is prohibited in public schools, except in specially designated areas. Restaurants with more than 50 seats are required to provide separate areas for smokers and nonsmokers.

According to a council memorandum, similar legislation has been approved by the local governments of Cambridge, Mass., Seattle and Dallas.

HATE-VIOLENCE -- The council unanimously approved legislation to extend the Anti-Hate Violence Fund Law until June 30, 1991.

The original law set up a fund in late 1982 to offer monetary rewards for tips leading to the arrest of people who perform acts against an individual or an institution because of race, religion or ethnic background. Such acts include swastika-painting, cross-burnings, arson, telephone threats, assaults, racial name-calling and distribution of Ku Klux Klan and Nazi literature.

The law had been scheduled to expire June 30.

A report by the county Office of Legislative Oversight recommended that the law be amended to clarify that money from the fund may be used to publicize that the fund exists. Council members included an amendment in the bill that allows for 10 percent of the fund to be used for such publicity and that any additional publicity funds would have to be approved by the county's chief administrative officer.

The fund was started with $50,000. Last month, it showed a balance of $44,902. Since 1983, the Office of Legislative Oversight reported, the fund has been used to pay rewards for information leading to arrests in five cases.
