(2) A SWSAP PWS may apply to the State Board, for written approval, for a reduced on-going alternative minimum theoretical retention time of less than 180 days, but no less than 60 days. The SWSAP PWS's application shall include all information requested-by the State Board for its consideration of a proposed alternative minimum theoretical retention time, including the he following: A Evidence that the SWSAP PWS and SWSAP WRA have reliably- and consistently met the requirements of this Article and Article 5.3, Chapter 3, under varying operating conditions: (B)At the proposed alternative minimum theoretical retention time; the maximum anticipated recycled municipal wastewater flow to the surface water reservoir, the total anticipated outflows from the reservoir, and the total available flows of approved reservoir sources of supply: (C) The maximum percent, by volume, of recycled municipal wastewater that will be delivered to the surface water reservoir during any 24-hour period, in accordance with subsection (c), at the proposed alternative minimum theoretical retention time: (D)_A description of total proposed treatment and total l09o reduction for enteric virus, Giardia cysts, and Cryptosporidium oocysts. For proposed alternative Regulation Text 28 of 31 SBDDW-16-02 Surface Water Augmentation Using Recycled Water October 31, 2017 minimum theoretical retention times less than 120 days, no less than one to io reduction of such atho ens beyond that otherwise required pursuant to this Article and Article 5.3,Chapter 3, shall be provided; (E) The ability to adequately respond to potential SWSAP treatment failures in a_timely_manner, such that there is no interruption of drinking water, meeting all applicable standards, supplied to customers; and (F) A demonstration that the alternative minimum theoretical retention time provides, based on information provided pursuant to this paragraph (paragraph (2)), an equivalent or better level of protection of public health than otherwise required pursuant to this Article and Article 5.3, Chapter 3. If required by the State Board, the SWSAP PWS's demonstration shall include a review by an independent scientific adviso[Y panel approved by the State Board. (c) Prior to augmentation, and whenever requested to do so by the State Board based on information that previous tracer studies or hydrodynamic modeling may not accurately reflect current conditions, the SWSAP PWS shall demonstrate to the State Board, utilizing tracer studies and hydrodynamic modeling, that at all times under all operating conditions, the volume of water withdrawn from the augmented reservoir to be ultimately supplied for human consumption contains no more than: (1) one percent, by volume, of recycled municipal wastewater that was delivered to the surface water reservoir during any 24-hour period, or (2) ten percent, by volume, of recycled municipal wastewater that was delivered to the surface water reservoir during any 24-hour period, with the recycled municipal wastewater delivered b_V the SWSAP WRA having been subjected to additional treatment producing no less than a 1-login reduction of enteric virus, Giardia cysts, and Cryptosporidium oocysts, as noted pursuant to section 60320.308(a)(2). With regard to the additional treatment: (A) The additional treatment need not be a unique type of process from other treatment processes utilized by the SWSAP WRA to meet the requirements of section 60320.308, bwt shall 6- ".. s...,...,de-aa of and- , ' r—1-pianh ...than...,,,.}w.

Regulation Text 29 of 31 SBDDW-16-02 Surface Water Augmentation Using Recycled Water October 31, 2017 (B) The SWSAP PWS, in consultation with the SWSAP WRA, shall obtain the additional treatment process information necessary for demonstrating that the re uirements of section 60320.308(a)(2) of Chapter 3 and this paragraph will be met. (d) To verify that the requirements of subsection (c) are being met, within the first six months of operation, under hydraulic conditions representative of normal SWSAP operations, the SWSAP PWS shall initiate a tracer study utilizing an added tracer. The results of the tracer study shall be used to validate the hydrodynamic modeling required in subsection (c). Prior to performing the tracer study, the SWSAP PWS shall submit a tracer study protocol for State Board review and written approval. The SWSAP PWS shall perform the verification required by this subsection whenever re-q-uested by the State Board. (e) Notwithstanding a change in operation allowed pursuant to the SWSAP PWS's domestic water supply ermit rior to initiating a change in operation, including physical changes to the surface water reservoir, that may impact the hydraulic characterization utilized to determine compliance with the requirements of this section, the SWSAP PWS shall notify the State Board and; (1) demonstrate that the hydraulic characterization used to comply with this section remains valid under the changed operation, or (2) if requested by the State Board, demonstrate compliance pursuant to this section under the new hydraulic conditions. (f) Unless directed otherwise by the State Board, a SWSAP PWS shall utilize an independent scientific advisory panel to meet the requirements of this section pertaining to the hydraulic characterization of the reservoir, including tracer study verifications_and hydraulic modeling„used,to„demonstrate compliance with subsection (c). The independent scientific advisory panel shall be approved by the State Board and include at a minimum, a limnologist with experience modelling the hydraulic characterization of surface water reservoirs, or a limnologist and an individual with experience modelling the hydraulic characterization of surface water reservoirs. The SWSAP PWS shall allow Regulation Text 30 of 31 SBDDW-16-02 Surface Water Augmentation Using Recycled Water October 31, 2017 State Board representatives, as quests, to loin all independent scientific advisory panel meetings and discussions. (g) Prior to augmentation of a surface water reservoir usinq a SWSAP, a SWSAP PWS shall submit a plan, for State Board review and approval, describing the actions the SWSAP PWS will take to assess and address potential impacts resulting from the introduction of advanced treated water into the SWSAP PWS's surface water treatment plant and, indirectly, into the drinking water distribution system. At a minimum, the plan shall address: (1) maintaining chemical and microbial stability in the drinking water distribution system as the drinking water quality changes with anticipated increasing fractions of advanced treated water; (2) maintaining treatment effectiveness throughout the surface water treatment plant as the source water quality changes with anticipated increasing fractions of advanced treated water in the reservoir, (3) assessments to be performed prior to.and during operation of the SWSAP with respect to paragraphs (1) and (2); and (4) assessment outcomes of which the SWSAP PWS will notify the State Board.
