Section 19June 23, 1999, Sec./Art. 19

Pollution From Stationary Sources. - The Department shall, within two (2) years from the effectivity of this Act, and every two (2) years thereafter, review, or as the need therefore arises, revise and publish emission standards, to further improve the emission standards for stationary sources of air pollution. Such emission standards shall be based on mass rate of emission for all stationary source of air pollution based on internationally accepted standards, but not be limited to, nor be less stringent than such standards and with the standards set forth in this section. The standards, whichever is applicable, shall be the limit on the acceptable level of pollutants emitted from a stationary source for the protection of the publics health and welfare.

With respect to any trade, industry, process and fuel-burning equipment or industrial plant emitting air pollutants, the concentration at the point of emission shall not exceed the following limits:
