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.\n(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.","path":["Health and Safety Code - HSC","DIVISION 26.
