A three tiered system?

Of course as soon as I post that I do not have an update I pick up a few updates. According to the SWRCB they are still working on the draft and do not have a date. Having said that I just saw an update at our county Board of Supervisors meeting where one Supervisor said that late April or May is possible. I have also heard from two sources that a three tiered system is being entertained. The tiers would range from no action to vigorous action based on the environmental impact of the situation. Tier one at least would not require any proactive measure such as routine testing. Once again I stress that this is just what is being talked about and we won't know how this will end up until we get the official word from the SWRCB.
