As for what's allowable, we've learned that there actually are regulations that apply, even to government:
"...if the receiving water is a Section 303 (d) impaired water, the COCs that impair the water must also be monitored..." (COC = contaminants of concern)
"...you can find the standards at the following URL:
"...This URL also discusses the “antidegradation” policy, which means no matter what the source, you cannot impact the water quality of the “receiving water”
"Bottom line, per the water quality codes, no human can impact the water quality of a surface water feature ..."
We'll keep sharing what we learn. Here's to science, reason, and truth.
