    RULE ANALYSIS

    Purpose of the rule or reason for the change:

    The proposed amendments are being made to bring Utah's Water Quality Standards into conformance with the Environmental Protection Agency (EPA) guidance, add clarifying language, and update stream classifications based on current information.

    Summary of the rule or change:

    The changes: 1) several tributaries to Escalante River, Saleratus Creek, and the State Canal are added to the stream classifications; 2) lakes and reservoirs greater than 10 acres and not listed specifically have a default listing equal to the classification of the stream with which they are associated (instead of 20 acres); 3) maximum E. coli numeric criteria is changed from a regulatory value to a pollution indicator; 4) the total dissolved solida (TDS) numeric criteria are revised to eliminate the irrigation and stockwatering descriptions, eliminate the stockwater value of 2,000 mg/l and retain the 1,200 mg/l as applicable to all Class 4 waters; 5) define laboratory procedures as those approved at required detection levels instead of by actual analytical instrument; 6) remove the adjustment of TDS limits if such adjustment does not impair the designated beneficial use of the receiving water; 7) add Antelope Creek, Indian Canyon Creek, Paria River, Soldier Creek, Coal Creek, Pinnacle Creek, Gordon Creek with site specific TDS criteria; 8) clarify that the total phosphorus indicator in streams and reservoirs is a pollution indicator; 9) clarify the need for quantification of possible human E. coli impact in National Wildlife Refuges and State Water Management Areas; 10) approves the measurement of E. coli using the Quanti-Tray/2000 procedure as a field method; 11) add Diazinon and Nonylphenol as water quality numeric criteria; and 12) clarify mathematical exponential calculations to a more common format.

    State statutory or constitutional authorization for this rule:

    Section 19-5-104

    Anticipated cost or savings to:

    the state budget:

    There is no anticipated cost or savings to state budget. The proposed amendments will be implemented using existing resources.

    local governments:

    The Division does not anticipate that the proposed amendments will significantly alter how this rule will be applied to local governments. Therefore, no savings or costs to local government are projected.

    other persons:

    Removal of language allowing adjustment of TDS limits, if such adjustment does not impair the designated beneficial use of the receiving water, has the potential to impact dischargers. Dischargers will be required to meet effluent limits based strictly upon the numeric water quality standard of the receiving water. In some cases, the discharger may be required to have a more stringent effluent limit than currently allowed. The actual amount of additional cost is a function of case-by-case conditions and cannot be exactly projected. However, increased costs associated with this change are not likely as the rule still allows for TDS standards to be set at background where it can be shown that natural or unalterable conditions prevent its attainment.

    Compliance costs for affected persons:

    Removal of language allowing adjustment of TDS limits if such adjustment does not impair the designated beneficial use of the receiving water has the potential to impact dischargers. Dischargers will be required to meet effluent limits based strictly upon the numeric water quality standard of the receiving water. In some cases, the dischargers may be required to have a more stringent effluent limit than currently allowed. The actual amount of additional cost is a function of case-by-case conditions and cannot be exactly projected. However, increased costs associated with this change are not likely as the rule still allows for TDS standards to be set at background where it can be shown that natural or unalterable conditions prevent its attainment.

    Comments by the department head on the fiscal impact the rule may have on businesses:

    The majority of the proposed amendments are editorial, provide clarifying language or update/add stream classifications based on current information. No fiscal impacts to businesses from these changes are anticipated. Removal of language allowing adjustment of TDS limits if such adjustment does not impair the designated beneficial use of the receiving water has the potential to impact dischargers. The actual amount of additional cost is a function of case-by-case conditions and cannot be exactly projected. However, increase costs associated with this change are not likely as the rule still allows for TDS standards to be set at background where it can be shown that natural or unalterable conditions prevent its attainment.

    R317-2-3. Antidegradation Policy.

    3.1 Maintenance of Water Quality

    . . . . . . .

    The ADR will cover the following requirements or determinations:

    1. Will all Statutory and regulatory requirements be met?

    The Executive Secretary will review to determine that there will be achieved all statutory and regulatory requirements for all new and existing point sources and all required cost-effective and reasonable best management practices for nonpoint source control in the area of the discharge. If point sources exist in the area that have not achieved all statutory and regulatory requirements, the Executive Secretary will consider whether schedules of compliance or other plans have been established when evaluating whether compliance has been assured. Generally, the "area of the discharge" will be determined based on the parameters of concern associated with the proposed activity and the portion of the receiving water that would be affected.

    2. Are there any reasonable less-degrading alternatives?

    There will be an evaluation of whether there are any reasonable non-degrading or less degrading alternatives for the proposed activity. This question will be addressed by the Division based on information provided by the project proponent. Control alternatives for a proposed activity will be evaluated in an effort to avoid or minimize degradation of the receiving water. Alternatives to be considered, evaluated, and implemented to the extent feasible, could include pollutant trading, water conservation, water recycling and reuse, land application, total containment, etc.

    For proposed UPDES permitted discharges, the following list of alternatives should be considered, evaluated and implemented to the extent feasible:

    (a) innovative or alternative treatment options

    (b) more effective treatment options or higher treatment levels

    (c) connection to other wastewater treatment facilities

    (d) process changes or product or raw material substitution

    ([e) seasonal or controlled discharge options to minimize discharging during critical water quality periods

    (f]e) seasonal or controlled discharge options to minimize discharging during critical water quality periods

    ([g]f) pollutant trading

    ([h]g) water conservation

    ([i]h) water recycle and reuse

    ([j]i) alternative discharge locations or alternative receiving waters

    ([k]j) land application

    ([l]k) total containment

    ([m]l) improved operation and maintenance of existing treatment systems

    ([n]m) other appropriate alternatives

    An option more costly than the cheapest alternative may have to be implemented if a substantial benefit to the stream can be realized. Alternatives would generally be considered feasible where costs are no more than 20% higher than the cost of the discharging alternative, and (for POTWs) where the projected per connection service fees are not greater than 1.4% of MAGHI (median adjusted gross household income), the current affordability criterion now being used by the Water Quality Board in the wastewater revolving loan program. Alternatives within these cost ranges should be carefully considered by the discharger. Where State financing is appropriate, a financial assistance package may be influenced by this evaluation, i.e., a less polluting alternative may receive a more favorable funding arrangement in order to make it a more financially attractive alternative.

    It must also be recognized in relationship to evaluating options that would avoid or reduce discharges to the stream, that in some situations it may be more beneficial to leave the water in the stream for instream flow purposes than to remove the discharge to the stream.

    (2) These limits are not applicable to lower water levels
    in deep impoundments. First number in column is for when
    early life stages are present, second number is for when all
    other life stages present.
    (3) The temperature standard shall be at background where
    it can be shown that natural or un-alterable conditions
    prevent its attainment. In such cases rulemaking will be
    undertaken to modify the standard accordingly.
    Site Specific Standards for Temperature
    Ken's Lake: From June 1st - September 20th, 27 degrees C.
    (4) Where criteria are listed as 4-day average and
    1-hour average concentrations, these concentrations should not
    be exceeded more often than once every three years on the
    average.
    (5) The dissolved metals method involves filtration of
    the sample in the field, acidification of the sample in the
    field, no digestion process in the laboratory, and analysis by
    [atomic absorption spectrophotometry or inductively coupled
    plasma (ICP).
    ] EPA approved laboratory methods for the required
    detection levels
    .
    (6) The criterion for aluminum will be implemented as follows:
    Where the pH is equal to or greater than 7.0 and the
    hardness is equal to or greater than 50 ppm as CaC03 in the
    receiving water after mixing, the 87 ug/1 chronic criterion
    (expressed as total recoverable) will not apply, and aluminum
    will be regulated based on compliance with the 750 ug/1 acute
    aluminum criterion (expressed as total recoverable).
    (7) Hardness dependent criteria. 100 mg/l used.
    Conversion factors for ratio of total recoverable metals to
    dissolved metals must also be applied. In waters with a
    hardness greater than 400 mg/l as CaC03, calculations will
    assume a hardness of 400 mg/l as CaC03. See Table 2.14.3 for
    complete equations for hardness and conversion factors.
    (8) Reserved
    (9) The following equations are used to calculate Ammonia
    criteria concentrations:
    (9a) The thirty-day average concentration of total ammonia
    nitrogen (in mg/l as N) does not exceed, more than once every
    three years on the average, the chronic criterion calculated
    using the following equations.
    Fish Early Life Stages are Present:
    mg/l as N (Chronic) = ((0.0577/1+107.688-pH)+ (2.487/1+10PH-7.688))
    * MIN (2.85, 1.45*100.028*(25-T) )
    Fish Early Life Stages are Absent:
    mg/1 as N (Chronic) = ((0.0577/1+107.688-pH) + (2.487/1+10pH-7.688))
    * 1.45*100.028* (25-MAX(T,7)))
    (9b) The one-hour average concentration of total ammonia
    nitrogen (in mg/l as N) does not exceed, more than once every
    three years on the average the acute criterion calculated
    using the following equations.
    Class 3A:
    mg/l as N (Acute) = (0.275/(1+107.204-pH)) + (39.0/1+10pH-7.204))
    Class 3B, 3C, 3D:
    mg/l as N (Acute) = 0.411/(1+107.204-pH)) + (58.4/(1+10pH-7.204))
    In addition, the highest four-day average within the 30-day
    period should not exceed 2.5 times the chronic criterion.
    The "Fish Early Life Stages are Present" 30-day average total
    ammonia criterion will be applied by default unless it is
    determined by the Division, on a site-specific basis, that it
    is appropriate to apply the "Fish Early Life Stages are
    Absent" 30-day average criterion for all or some portion of
    the year. At a minimum, the "Fish Early Life Stages are
    Present" criterion will apply from the beginning of spawning
    through the end of the early life stages. Early life stages
    include the pre-hatch embryonic stage, the post-hatch free
    embryo or yolk-sac fry stage, and the larval stage for the
    species of fish expected to occur at the site. The division
    will consult with the Division of Wildlife Resources in making
    such determinations. The Division will maintain information
    regarding the waterbodies and time periods where application
    of the "Early Life Stages are Absent" criterion is determined
    to be appropriate.
    (10) Investigation should be conducted to develop more
    information where these levels are exceeded.
    (11) pH dependent criteria. pH 7.8 used in table. See
    Table 2.14.4 for equation.
    (12) Total Phosphorus as P (mg/l) as a pollution indicator
    for lakes and reservoirs shall be 0.025.
    (13) Formula to convert dissolved sulfide to un-disassociated
    hydrogen sulfide is: H2S = Dissolved Sulfide * e((-1.92 + pH) + 12.05)
