Sand & Gravel General Permit history

We issued the Modified Sand and Gravel Permit on Jan. 19, 2018.

Modifications to the 2016 permit

Will I be affected by the modified permit?

The majority of permittees will not be affected. The following types of permittees will see some changes:

  • Asphalt batch plants and asphalt recycling operations that discharge process water to the ground.
  • New concrete recycling operations receiving coverage for the first time.
  • Portable batch plants and portable rock crushers that move from location to location.   

Why did the permit change?

The 2016 permit was appealed by the Washington Aggregate and Concrete Association. A settlement was reached on modified language for the permit in August 2017. 

The modified language allows more flexibility for portable operations and new concrete recyclers.

The appeal resulted in modifications to:
  • pH monitoring for asphalt batch plants and asphalt recycling (S2, Table 2)
  • Concrete recycling best management practices (S8.F)
  • Coverage for portable facilities (S12.B) and related coverage forms
We accepted public comment on the permit modifications Sept. 26, 2017 through Dec. 8, 2017. We held a public workshop and hearing on Nov. 30, 2017.
