> methodology of application of these waste products Linked document is interesting, however it is "Brine Application Equipment and Methodology" - methodology of deicing paved roads. Only mention of toxic or waste is an aside of brine use motivation - granular material in California is for some reason regulated as toxic waste. Mentioned in the document are NaCl, MgCl₂, CaCl₂ brines and beet juice, and in the survey section, some agencies also report use or discontent with proprietary deicing products. Going by the second document, O&G wastewater use on roads is not permitted in California. In the 13 states that do allow its use, the study mostly mentions use on unpaved roads as a dust suppressant in lieu of salt brine (neither a particularly good idea IMO).
