(a) Neither the state board nor any district shall impose a discharge requirement on emissions of visible smoke from diesel pile-driving hammers which is more stringent than the requirements of this section, except as provided in subdivisions (b) and (c).
(b) A district shall issue a permit to the operator of a diesel pile-driving hammer if the operator submits a completed application for a permit to the district and the district determines, on the basis of information provided in the application, that the proposed use will comply with one of the following requirements:
(1) Meets the Ringelmann 1 limit, as published by the United States Bureau of Mines, and does not exceed that limit for more than four minutes during the driving of a single pile.
(2) Meets the Ringelmann 2 limit, as published by the United States Bureau of Mines, does not exceed that limit for more than four minutes during the driving of a single pile, and uses kerosene fuel, smoke suppressing fuel additives, and synthetic lubricating oil. A district may establish other requirements for compliance with this paragraph if the requirements are technologically and economically feasible. A district may consider the type of soil in which the pile driving is to occur and the number of blows required to drive a pile in determining the technological and economic feasibility of other conditions to be imposed by the district.
(c) A permit issued by a district shall be valid until the pile-driving work has been approved or accepted by the person or entity for which the work is being performed. Upon request of an operator or of a person or entity for which the pile-driving work is performed, a district may extend the time period for which the permit is valid if the operator continues to comply with this section.
