Yep thats what we have to do up here in N. California. We also have to filter approx. 143+ chemicals from the water before we can discharge to the local sewer. And if you pressure wash, you cannot move ANY substance from point A to point B EVEN though it did not leave the property. You dislodge it, you pick it up. In some cities it is Illegal to rinse or wash your car on your own property. Thats what car washes are for.
However, I was told that we are far behind from most other states. The problem for me is, I can't find those states.
In fact, California already has some of the strictest air quality exhaust emissions than any other state, especially diesel and small gas engines. When you have 54 electoral votes, you tend to have more business thus have to implement more restrictions on pollution in order to keep it healthy. The City of Palo Alto ( Stanford Area ) has a ordinance prohibiting usage of commercial small engines 1 day a week. This is to help with air pollution and noise.
Last night, because of the weather pattern blowing in from the east instead of the west ( "spare the air" day ), the air was considered unhealthy. The Bay Area was put on notice to cease all wood burning fireplaces. The dept. sent out hundreds of people with flashlights to check for people burning a fire in their fireplaces. 1st offense on record, just a notice. 2nd offense $100. 3rd $500, 4th 1,000. This includes camp fires.
Newer homes are now being built without fireplaces in them due to pollution.
