Talked to city fire Marshall....No Problem on private RESIDENTIAL property, but "may" need a noise variance...... Also deferred to state fire marshall.
Fire inspector was thinking possible "pyro" permit because of no familiarity with definition of "special effect" which is a special configuration of fireworks, not flame effect.
Also deferred to state fire marshall. Oregon definition of fireworks is "composition or substance or any article providing a visible or audible effect by combustion, etc.... WA is similar....
NFPA 1126 - fireworks/pyrotechnics,; specifically excludes gaseous or liquid fuels
