Stormwater Generates Heat
Our own Ken Moon (MPCA), compliance coordinator reported through an EPA stormwater list serv (which you may have received) that staff inspected 25 percent of sites covered by an NPDES stormwater construction permit:

We are inspecting about 25% of the CSW sites annually using the States inspection program (this is impressive after phase II) and this presence is being felt by the regulated parties. It is generating other partnerships within the building communities, one example is a request for joint CSW training, as pressure by their members to avoid delays and (I would like to think) enforcement has prompted them to request it.

In Moon's report he said that, in part, because of help from members of a pilot partnering (PCA has partnered with a handful of SWCDs, counties, cities, watershed districts to have them do site inspections) arrangement, the stormwater program has become the top generator of enforcement actions at the PCA.
