Ideally both, but the article will focus mostly onthe governmental process Lomake rules about emerging
contaminants. I would love an estimate on both if you can though.

Thank you againforthiul/h/uklundorstanditprnttvvrell.l1lhavntolonkupsnmeofthcscc000mitteos,hut
Iget the basic outline now. Also, iLlooks like this was laid out in'79and then modified afew times through
the early ROs.Not sure if you'd know, but has this basically been pretty stable since then?
OEQ-CFVV_00013803

Also, and again I'm not sure i f you'd know, but is there a sense of what the time table might be like? (i.e. from
a staff recommendation to GA approval to EPA/Fish and Wildlife review).

See Q and A below. Let us know if you need anything else.
What steps would it take to come up with a state surface/groundwater, or drinking water standard for
GenX?
Surface or groundwater standards (rule citations incorporated)
The authority to establish new or amended groundwater (15 A NCAC 02L) and surface water (I 5A NCAC
02B) standards falls under the authority of the Environmental Management Commission (EMC). Most
research and background information for surface water is generated by the U.S. EPA (under the Clean Water
Act) and published as national recommended water quality criteria.
There is no federal analog to the state's groundwater standards program, however, the U.S. EPA publishes
some toxicity values that may be used in the derivation of groundwater quality standards. In both sets of rules,
mechanisms to establish provisional numbers are available. There are numerous steps that are required. A
brief description is below.
First, staff must have valid, peer -reviewed toxicological information to provide a recommended value to the
EMC. This recommendation takes time to gather, then staff must write up the justification and evaluate
research papers published in scientific journals. Consultation with other research scientists and agencies is
common. It often involves conversations with state laboratories, and commercial laboratories to determine if
we can analyze for the chemical of concern with confidence.
The Water Quality Committee (or the Groundwater Committee) of the EMC must approve us to proceed to
the full EMC for approval to go out to public hearings with any revised water quality standard. Prior to public
hearings or approval of any recommended changes, a fiscal note must be prepared and approved by the
commission and the Office of State Budget Management.
After public hearings are held, an information package is prepared and presented to the EMC for amendment,
approval or disapproval. If approved, the final regulations must go through the Rules Review Commission
(RRC) and potentially the General Assembly, before changes to current rules can be enforced. If the package
of rules is for surface water amendments (I 5A NCAC 02B), a review and approval by the N.C. Attorney
DEQ-CFW-00013804

General's office, the U.S. EPA and the U.S. Fish and Wildlife Service is required under the Clean Water Act
and the Endangered Species Act.
Drinking water standards
The national drinking water program requirements are specified in the federal Safe Drinking Water Act and
EPA's national primary drinking water regulations. Essentially, EPA does the research and analysis to set
standards applicable to public water systems and state primacy agencies implement the programs to monitor
and evaluate compliance and take appropriate enforcement actions.
The Public Water Supply staff consists of engineers and environmental specialists with expertise related to
implementation of the Safe Drinking Water Act and the related rules based on the application of engineering
principles and practices.
