If State or local standards are not prescribed for a particular location, or if the State or local standards are less stringent than the standards prescribed herein, the standards in this part shall be applicable to discharges from such Federal facilities and buildings except as otherwise indicated.

(c) Temporary operations that may result in potential air pollution problems, such as those associated with research, development, test, evaluation, space, and military activities, shall be conducted with such precautions and safeguards as are needed to achieve the intent of these standards.

(d) The Administrator may, upon application of the relevant department, agency or establishment, exempt any Federal facility or building from any or all of these standards whenever he determines that the activities of such building or facility will not significantly conflict with the intent of the Executive order and that such an exemption is in the public interest. 8 76.4 Combustion of fuel.

(a) The following standards apply to the combustion units of facilities and buildings having a heat input of less than 1,000 million B.t.u./hour, other than fireplaces, stoves, or grills burning wood or charcoal:

(1) Manually fired equipment shall not be installed as new or replacement equipment, except for the burning of anthracite, coke, or smokeless fuel.

(2) (i) For new units, except during startup, cleaning of fires, or soot blowing, the density of any emission to the atmosphere shall not exceed No. 1 on the Ringelmann Scale.

(11) For existing units, except during startup, cleaning of fires, or soot blowing, the density of any emission to the

atmosphere shall not exceed No. 2 on the Ringelmann Scale.

(3) A photoelectric or other type smoke detector, recorder, or alarm shall be installed on units larger than ten million BTU per hour input, except where gas or light oil (No. 2 or lighter), is burned.

(4) During routine operation, tho emission of particles larger than 60 microns shall not normally occur.

(5) Means shall be provided in all newly constructed units and wherever practicable in existing units to allow the periodic measurement of flyash and other particulate matter..

(6) All new or replacement spreader stoker installations shall be of a type that automatically discharges ashes to the ash pit either continuously or in very frequent small increments, and flyash shall be reinjected only from boiler passes.

(7) For units of less than 10 million BTU/hour heat input, the emission of flyash and other particulate matter shall not exceed 0.6 pounds of particulate matter per million BTU heat input, as measured by the American Society of Mechanical Engineers Power Test Code No. 27 for “Determining Dust Concentrations in a Gas Stream," or equivalent test method.

(8) For units between 10 million and 1,000 million BTU/hour heat input, the emission of and other particulato matter shall not exceed that specified in figure 1, as measured by the test method specified in subparagraph (7) of this paragraph.

(b) For units having a heat input of more than 1,000 million BTU/hour, the appropriate department, agency, or establishment shall seek special advice from the Administrator with regard to smoke, flyash, and other particulate emissions.
