7. Manufacturing operations shall be curtailed, postponed, or deferred.
8. Trade waste disposal operations which emit solid particles, gas vapors or malodorous substances shall be deferred.
9. Heat load demands for processing shall be reduced.
(c) (2) Second Stage: Industrial Air Pollution Warning. Whenever the Commissioner declares an industrial air pollution warning persons responsible for the operation of a source of air pollution shall as rapidly as possible take all required steps for pollution reduction as described in table II. Persons responsible for the operation of a source of air pollution which emits, or has the capacity to emit, more than 100 tons of pollutants per year, as determined before the application of control equipment, shall put into effect the preplanned abatement strategy for an air pollution industrial warning.
Table II
Steps for Air Pollution Reduction at an Air Pollution Industrial Warning

3. Boiler lancing or soot blowing required for fuel-burning equipment shall be performed only between the hours of 12 noon and 4 p.m.
4. All unessential operation of motor vehicles shall be terminated.
5. Electric power generation shall, to the maximum extent possible, be diverted to facilities outside the warning area.
6. Steam load demands shall be reduced the maximum extent possible.
7. Manufacturing operations shall be ceased, curtailed, postponed, or deferred.
8. Trade waste disposal operations which emit solid particles, gas vapors, or malodorous substances shall be deferred.
9. Heat load demands for processing shall be reduced the maximum extent possible.
(c) (3) Third Stage Industrial Air Pollution Emergency. Whenever the Commissioner declares an industrial air pollution emergency, persons responsible for the operation of a source of air pollution shall immediately take all required steps for pollution reduction as described in table III, persons responsible for the operation of a source of air pollution which emits, or has the capacity to emit, more than 100 tons of pollutants per year, as determined before the application of control equipment, shall put into effect the preplanned abatement strategy for an industrial air pollution emergency.
Table III

(g) (2) Second Stage: Automotive Air Pollution Warning. An automotive air pollution warning shall be declared whenever evidence shows that air quality is continuing to degrade from the automotive air pollution advisory and alert one of the following levels is reached at any monitoring site operated by the Department of Environmental Protection: CO: 34 ug/m3 (30 ppm), 8-hour average;
