In many, probably most, cases of disturbed land the answer is as simple as erosion control. Matters are complicated by a rash of regulations. The California State Fish and Game Department and many counties prescribe that erosion control seeding shall occur between September 15th and October 15th, regardless of when construction was completed . The bare ground could face nearly a year of erosive elements that remove soil and dust. Smaller sites are subject to local regulations based on an EPA model erosion control ordinance.
Dust suppression is administered through the local air quality management authority.
At the moment, regional dust control is targeted in the south San Joaquin Valley, California's south coast, and in the Reno, Nevada area, but not in other regions. Local grading ordinances address water erosion. The same site may be subject to regulation by the EPA, state fish and game department, U.S. Fish and Wildlife Service, the county, air quality management district, regional water quality control board and perhaps a few others, such as the California Coastal Commission and the Army Corps of Engineers. The angel's job is to spot duplicate efforts and conflicting regulations being developed then visit the bureaucrats in their dreams and help them see a better way. But alas, angels, like open cooperation between government agencies, are little more than dreams under the current regulatory culture.
