Slide 8
Comments Received
General Comments:
 Is it inappropriate to make all these changes to the MRP based on the
limited number of inspections
 A few agencies are reporting a significant number of spills and spills to
surface waters. All agencies Should not be required to comply with
these new requirements
 The State Water Board should consider the cost to agencies of these
additional MRP requirements
 New requirements will burdensome and will take resources from other
resources intended to reduce SSOs
 Additional record keeping requirements will not reduce SSOs
 SWRCB provide guidance to the stakeholders on how to ascertain which
water bodies are a "water of the state"
 These changes deviate from the intent of the SSS WDRs, which is to
reduce the number of SSOs. Slide 9
