Summary of Concerns
A. Need for more discussion/clarification in general
B. Overall usefulness
C. Interpretation on how 131.10 language for removing a DU apply to variances (since 1976)
1) Strict interpretation—more conservative view of how variances are implemented
2) Flexible interpretation—focus on facility implementation, as opposed to a removal of a DU for a waterbody. It’s discharger and pollutant specific and for a limited time.
Specific Concerns
1. 131.10(h)(1) existing use language—“…variance may not result in any loss or impairment of an existing use.”
◦ How does this apply to a discharger variance, as opposed to removing a DU?
◦ How do you define “loss or impairment”?
◦ EPA HQ
2. 131.10(h)(2) – “…must demonstrate that implementation of all cost effective and reasonable BMPs for NPS cannot correct the underlying WQ problem”
◦ Previously discussed by EPA in GLI
◦ DEQ has revised language in variance regulation to reflect this interpretation
◦ EPA HQ
3. New facilities
◦ In principle, variances shouldn’t be allowed for new facilities, since the idea is to not further degrade a waterbody; however, are there exceptions?
i. Clean up sites?
ii. WWTP in lieu of onsite systems?
◦ Other states have included exceptions
I. Imminent threat to public health or welfare
II. CERCLA actions
◦ Other exceptions?
4. Renewal confirmation
5. AL applicability
◦ Thus far, the focus has been on meeting the revised HHC, but the proposed variance regulations, as w/ the current regulations, also includes the inclusion of possible variances based on the AL criteria
◦ We do not anticipate variances from AL criteria, but we would look critically at these requests and would work closely w/ EPA if any were requested. ESA consultation would be required.
◦ The decisional regulatory framework is there already
6. Duration of variance
◦ Coincide w/ NPDES permit
◦ Remains in effect as long as the permit is in effect
7. MDVs…
