permit was initially issued on March 27. 2008. and then renewed. on Januar\ 25. 2010_ and March 9, 2012, and expired on
February 28, 2014. Following the re\ iew of the performance monitoring data collected after the injection events_ the
Perm ittee has requested the permit be renewed with modification to include additional injections) into 7 existing wells and
6 new proposed wells. Since the permit for this injection activity has previously been approved and information contained
therein is essentialh• the same, 1 am attaching this modified memo reflecting those proposed changes from the previous
permit. Please refer to the previous permit issuance memorandum f()r more information on this site,

to ensure that you are aware of all compliance requirements of the permit.
Please note the following:
a Per permit condition Part V1.5. prior to closing this permit, the Permittee must meet
groundwater quality standards or pre -injection levels. whichever concentration is higher, for all
of the injection constituents, otherwise, continued monitoring as approved in the monitoring
plan will be required until such levels can he established;
+ Per permit conditions Part VL.3 &4, and I\.2(G), within 30 dams after each injection event.
please provide the well construction (if not previously submitted) and injection information on
the applicable forms listed below. Note: if well constructionlabandonmen t information is
essentially the same (e.g.. direct push points or geo-probes), then only one GW-1 or GW-30
form is needed. Just indicate in the comments section on the form the total number of well
points. These forms are available on the Division of Water Resources' Website at
