(1) Immediate emergency work necessary to protect life or property.

(2) Immediate emergency repairs to public service facilities necessary to maintain service as a result of a disaster in an area in which a state of emergency has been proclaimed by the Governor pursuant to Chapter 7 (commencing with Section 8550) of Division 1 of Title 2 of the Government Code.

(3) Emergency projects undertaken, carried out, or approved by a state or local governmental agency to maintain, repair, or restore an existing highway, as defined in Section 360 of the Vehicle Code, within the existing right-of-way of the highway, that has been damaged as a result of fire, flood, storm, earthquake, land subsidence, gradual earth movement, or landslide, within one year of the damage. Work needed in the vicinity above and below a highway may be conducted outside of the existing right-of-way if it is needed to stop ongoing or recurring mudslides, landslides, or erosion that pose an immediate threat to the highway, or to restore those roadways damaged by mudslides, landslides, or erosion to their predamage condition and functionality. This paragraph does not exempt from this chapter any project undertaken, carried out, or approved by a state or local governmental agency to expand or widen a highway damaged by fire, flood, storm, earthquake, land subsidence, gradual earth movement, or landslide. The exception provided in this paragraph does not apply to a highway designated as an official state scenic highway pursuant to Section 262 of the Streets and Highways Code.

(b) The entity performing the emergency work described in subdivision (a) shall notify the department of the work, in writing, within 14 days of beginning the work. Any work described in the emergency notification that does not meet the criteria for the emergency work described in subdivision (a) is a violation of this chapter if the entity did not first notify the department in accordance with Section 1602 or 1611.

(c) This chapter does not apply to activities undertaken pursuant to Section 1242.1 or 1432 of the Water Code.

1432.

 (a) A permit for a diversion to groundwater recharge that is issued pursuant to this article shall meet both the following conditions:

(1) Diverted water shall not be diverted or applied to any of the following:

(A) Any barns, ponds, or lands where manure or waste from an animal facility that generates waste from the feeding and housing of animals for more than 45 days per year in a confined area that is not vegetated are applied.

(B) An agricultural field that has been identified as an outlier with respect to nitrogen application by any of the following:

(i) The board.

(ii) The appropriate regional board.

(iii) An agricultural coalition charged with implementation of the Irrigated Lands Regulatory Program.

(C) An area where the diversion could cause damage to critical levees, infrastructure, wastewater and drinking water systems, or drinking water wells or drinking water supplies, or exacerbate the threat of flood and other health and safety concerns.

(D) An area that has not been in active irrigated agricultural cultivation within the past three years, including grazing lands, annual grasslands, and natural habitats. This limitation does not apply to facilities already constructed for the purpose of groundwater recharge or managed wetlands.

(2) The diversion utilizes all of the following:

(A) Either existing diversion infrastructure or temporary pumps.

(B) Existing groundwater recharge locations, where available.

(C) No new permanent infrastructure or permanent construction.

(D) For diversions from rivers and streams, protective screens on temporary pump intakes to minimize the impacts of diversion on fish and other aquatic life. Those screens shall be constructed of any rigid material, perforated, woven, or slotted, that provides water passage while physically excluding fish. The screen face shall be parallel to the flow and adjacent to the water’s edge. The upstream and downstream transitions to the screen structure shall be designed and constructed to minimize eddies upstream of, in front of, and downstream of, the screen, while minimizing entrainment to the degree feasible. The protective screens shall follow recommendations and any other guidelines provided by the Department of Fish and Wildlife pursuant to paragraph (4) of subdivision (e) of Section 1242.1.

(b) (1) The board shall document that it complied with subdivision (b) of Section 1427 in approving the permit in subdivision (a).

(c) On or before January 1, 2027, the board shall compile information on the permits issued and diversions conducted pursuant to this section and post the information on its internet website. The board may include recommendations to increase the amount of water diverted for recharge while protecting groundwater quality, public safety, and fish and wildlife resources in this report. The board may consult with the Department of Fish and Wildlife in preparing the posted information.

(d) This section shall only apply to diversions commenced before January 1, 2029.
