Fairfax County's new ordinance places provoked more questions yesterday on how and where it applies rather than any barrage of calls for or against the ban.

The ordinance, passed by the county Board of Supervisors on Monday night by a 6-to-3 vote, becomes effective in 59 days.[TEXT OMITTED FROM SOURCES] calls have been trickling in all day, but most of them are from people wanting to knoe where and when you can or can't smoke," said county spokesman Edmund L. Castillo. "It's not anything like the calls we got when the Board passed mandatory water restrictions."

Violators of the no-smoking ordinance, modeled after one passed by Montgomery County on May 5, can be fined up to $25.

It prohibits smoking in retail and food stores in which more than eight persons are employed at any given time. Smaller retail and food stores are exempt.

Places included in the ordinance are elevators (except those in single-family houses); health care facilities, meetings attended by ore than eight persons.

Smoking also is prohibited in theaters, art galleries, libraries, museums and similar cultural facilities that receive any public funds.

Restaurants and public schools are not subject to the ban. The Montgomery County ordinance covers public schools.

"I expect we'll get some calls when people go to a restaurant and see it doesn't apply there," siadboard member Marie B. Travesky who voted for the ordiance. "We'll only get a couple of alls until then."

The ordinance also exempts "lawfully designated smoking areas," offices or work areas not entered by the public, theater loccies, tobacco shops, public, places at hours when they are not open to the public, patient sleeping quarters in many health-care facilities, and areas of enclosed shopping malls outside stores.

Passage of the ordinance followed a public hearing at the Massey Building at which all but a handful of about 40 persons who spoke expressed support for it.

Three opponents represented manufacturers or distributors of tobacco products.

Many professed nonsmokers speaking at the hearing, attended by about 200 people, expressed regreat that the ordiance was no more restrictive.

Board Chairman John F. Herrity, one of the three Board members who voted against the ban, said he believed the Board was not "doing anything of substance."

He added: "We're probably causing more incovenience than doing anything substantial."

Also voting against the ordinance were Supervisors Joseph Alexander (D-Lee) and John P. Shacochis (R-Drannesville).

The new ordinance is to be "mostly self-enforced," according to Mary Markham, an aide to County Executive Leonard Whorton.

Although complaints can be filed against persons violating the ordinance, Whorton expressed the view that "most people will obey the law" voluntarily.

The Montgomery ordinance has not been enforced sine passage, according to Richard Helfrich a section chief in the county's environmental protection division.

"We just got clearance to issue citions last week," he said in an interview, "Up until now it has been mostly an informational campaign . . . "

The District for several years has had an ordinance banning smoking in public places in the city was introduced in 1975, but it died in committee.

Councilman Jerry A. Moore (R-atlarge) re-introduced it earlier this year and he says that he believes it will go to a Council vote by the end of the year. The new version of the bill generally would outlaw smoking in public places, but would give eating establishments the option of creating smoking on no-smoking areas.
