104 STAT. 3302 PUBLIC LAW 101-618—NOV. 16, 1990 (iii) For purposes of this paragraph, the existing method of disposal shall include, in addition to underground leach field disposal, surface spray or sprinkler infiltration of treated wastewater on the site between Martis Creek and the Truckee River referred to in this subsection. (iv) The provisions of this paragraph requiring the acquisition of water rights or the extraction and discharge of groundwater to offset reductions in the amount or timing of return flow to the Truckee River shall also apply to entities other than TTSA that may treat and dispose of wastewater within the California portion of the Truckee River basin, but only if and to the extent that the treated wastewater is not returned to the Truckee River or its tributaries, as to timing and amount, substantially as if the wastewater had been treated and disposed of by TTSA in its existing place of disposal and by its existing method of disposal. The provisions of this paragraph shall not apply to entities treating and disposing of the wastewater from less than eight dwelling units. (H) All uses of water for commercial, irrigated agriculture within the Truckee River basin within California initiated after the date of enactment of this title shall not impair and shall be junior and subordinate to all beneficial uses in Nevada, including, but not limited to, the use of water for the maintenance and preservation of the Pyramid Lake fishery. As used in this provision, the term "commercial, irrigated agriculture" shall include traditional commercial irrigated farming operations but shall not include the following uses: irrigated golf courses and other recreational facilities, commercial nurseries, normal silvicultural activities other than commercial tree farms, irrigation under riparian rights on land irrigated at any time prior to the date of enactment of this title, lawns and ornamental shrubbery on parcels which include commercial, residential, governmental, or public buildings, and irrigated areas of two acres or less on parcels which include a residence. (I) Water diverted within the Truckee River basin and used to make snow shall be charged to California's Truckee River allocation as follows: (i) the first 225 acre-feet used in California each year shall not be charged to the gross diversion allocation; (ii) where water from the Truckee River basin is diverted and used to make snow in excess of the amounts specified in clause (i) of this subparagraph, the percentage of such diversions chargeable to such allocation shall be specified in the Operating Agreement; and (iii) the provision of subparagraph 204(c)(1)(F) notwithstanding, criteria for charging incidental runoff, if any, into the Lake Tahoe basin, including the amount and basin to be charged, from use of water in excess of the amount specified in clause (i) of this subparagraph, shall be specified in the Operating Agreement. The amounts of such water, if any, shall be included in each State's report prepared pursuant to paragraph 204(d)(1).
