Draft General Permit NCG14 for Ready -Mix Concrete Plants
The Public Water Supply Section has reviewed the referenced draft General Permit for Ready -
Mix Concrete Plants. We have no comment and concur with the provisions for dischargers to
water supply waters. It is our understanding that this General Permit covers activities which are
not expected to have a major ongoing impact to water supply waters. At the time that DEMLR is
reviewing submittals for applicability under the General Permit, if there are special concerns
presented by new or existing ready -mix concrete dischargers near public water supply intakes,
DEMLR and DWR should coordinate on appropriate alternative permitting actions. In addition,
if a certificate of coverage for General Permit NCGI4 would be issued within the critical area of
any Water Supply Watershed, DEMLR has agreed it will advise the Public Water Supply Section
so the Section may alert the public water system with sufficient time prior to permit issuance to
provide comments to DEMLR if the system believes that issuance of the General Permit could
have significant impact on the drinking water intake.
Thank you for the opportunity to comment.
