Description and Purpose
Prevent the discharge of pollutants to stormwater from
concrete waste by conducting washout onsite or offsite in a
designated area, and by employee and subcontractor training.
The General Permit incorporates Numeric Effluent Limits
(NEL) and Numeric Action Levels (NAL) for pH (see Section 2
of this handbook to determine your project's risk level and if
you are subject to these requirements).
Many types of construction materials, including mortar,
concrete, stucco, cement and block and their associated wastes
have basic chemical properties that can raise pH levels outside
of the permitted range. Additional care should be taken when
managing these materials to prevent them from coming into
contact with stormwater flows and raising pH to levels outside
the accepted range.

I believe allot is part of the federal clean water act.Several years ago a concrete supplier here in Denver got a hefty fine downtown.They were rinsing into hopper and final wash along street and busted.I will say it's a sticky situation these days.Some parts of the country are more lax than others.

I know here I am starting to see more washout pans,a sign of things to come,oh joy.I can't help but think about bp,our beloved friends.

I wash hoses and general spill into the drain, but never the hopper, too much concrete and too little water... :D
Seriously, better and cheaper to add retarder and take it with you.

the days of the old wash on the ground and go are just about over , I do understand the clean stormwater act and its purpose , I dont understand how we are still allowed to pour driveways and such with no vapor barrier to keep the concrete water from penetrating and maybe polluting our drinking water, things are changing but I really dont know how much these laws will improve our environment, I do know that in the very near future our most precious natural resource will be clean water, will washing out in a pan or bin save us all nope but it is a start in the rite direction, so there will be opponents but sorry to say for them they better get used to it cause thats just the way its gonna be. 

Can't comment on the residental jobs . Most jobsites in michigan let you wast out on the ground in a area away from strom sewers. Execpt in AnnArbor that has to be contianed. Started with the washout bags then switch over to a pan. The washout bags have extra labor costs involed. The crushers don't want them so the bags have to be stripped off. The pans are just plastic morture tubs just flip and strip. working for a contractor we have to clean up the mess so the pan or ground works for me. Just another day of work picking up the wash out with the dump and sktrak. Hate it but its work.

Thats why water washing back into the mixer can save everything. The leftover mud all goes back into a mixer were they can haul it of to a designated area. Also your hose, boom will be clean as well as your guts( valve, cylinders, transition.) Those being clean will give you time to goto or find a safe place to wash your hopper, cuase the only thing left in everything is water and gravel. They wont setup. I went 2 hrs and still washed right out after a waterwash. When you break your hoses they a just gravel no slurry washing down the street gutters or suck back the system then hook the candycane up with one hose back into the mixer fora you line pumpers. Hope it helped.

I'll have to say that working towards being cleaner (ie more green) is a noble task.  Do I think that the technology to truly and adequetly reach that task currently exist, not in the least.  I live and pump on an island in north west washington.  Storm water runoff issues are huge here.  Yet still, by state law, I can blow my boom and wash my hopper into a pit that has been dug on site by the contractor and be totally legal, but washing out on the ground is completely not and will cost me thousands if caught doing so.  Whats the difference between the surface and a hole in the ground.  I don't get it, and where do they think all that water that is takes to make concrete goes during the curing process.  True some goes to evap, but the large majority leachs into the ground (sub-grade).  Either make a set of rules that everyone (EVERYONE) must follow, or don't make any, and make to enforcement of those rules non-arbitrary.  One inspector says you're within the regs, the next one says you're not.  Whats right and whats wrong, and who's double checking and or training of the inspectors.  Seems to me they just interperet the law the way it works for them, and enforce it as such, so every inspector has a different idea about whats is ok.  How are we supposed to comply with that.  Might as well be shootin' darts drunk in a dark room!!!!
