Analytical Environmental Services ii City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment 1.0 INTRODUCTION

This Biological Resources Assessment (BRA) documents sensitive biological and special status species that have the potential to be affected by the proposed Wastewater Treatment Facility (WWTF) Upgrade Project (Proposed Project), located in the City of Shasta Lake, Shasta County, (Figure 1). This BRA has been prepared on behalf of the City of Shasta Lake (City) and may be used in support of permit applications and environmental review conducted in accordance with the California Environmental Quality Act (CEQA).

1.1 PROJECT LOCATION AND DESCRIPTION

The WWTF is located at 3700 Tibbitts Road within the incorporated boundaries of the City of Shasta Lake, Shasta County, California. The City-owned property consists of three parcels with corresponding assessor’s parcel numbers (APN) 064150070000, 064160005000, and 064160007000. For the purpose of this BRA, the study area only includes areas of the City’s property with the potential to be directly impacted by the Proposed Project. The approximately 106-acre study area is shown on Figures 2 and 3. The study area is bounded by Pine Grove Avenue to the north, Ashby Road to the west, and Churn Creek, a perennial stream that is a direct tributary to the Sacramento River, to the east. Regional access to the WWTF is provided by I-5. The study area is situated on Township 32 North, Range 5 West, Section 1 of the Shasta Dam U.S. Geological Survey (USGS) 7.5-minute topographic quadrangle (quad) (USGS, 1980). The centroid of the study area is 40° 39’ 46.7” North, 122° 23’ 00.4” West.

The existing WWTF was designed to meet Title 22 requirements for reuse purposes and is currently regulated on a variety of biological, chemical, and physical contaminant parameters under Central Valley Regional Water Quality Control Board (CVRWQCB) Order No. RS-201400052, National Pollutant Discharge Elimination System (NPDES) Permit No. CA0079511, and Time Schedule Order R5-2014-0052 adopted on March 28, 2014. Treated effluent at the WWTF is discharged into Churn Creek at two discharge points (001 and 002), and used to irrigate approximately 60-acres of sprayfields in the southeast portion of the study area. Additionally, the City provides recycled water to three contracted users. Under the current NPDES Permit, discharge of wastewater to Churn Creek, or its tributaries, is limited to the winter months (October 16th to April 14th) when the10:1 dilution requirement (receiving water to effluent flow) can be met. Sprayfield irrigation is used almost year round for the disposal of treated effluent, but especially during the summer months when the WWTF cannot discharge to Churn Creek.

The Proposed Project consists of various upgrades to the City’s WWTF which would result in the production of high-quality effluent that could be discharged to Churn Creek year-round under a direct discharge NPDES Permit with no dilution requirements. The spray fields and 400-acre-foot reclaimed water reservoir would be taken off line and abandoned in place. The City would continue to serve existing recycled water users using effluent that would be stored for short-term in the existing chlorine contact basin. Additionally, the Proposed Project includes a new effluent discharge pipeline, cascade re‐aeration structure, and replacement of the Churn Creek outfall at discharge point 001. The specific location of the replacement effluent discharge pipe alignment is still being determined. Discharge point 002 would be abandoned in place. As shown in Figure 3 and 4, with the exception of the improvements to the effluent pipeline and outfall structure in the riparian area of Churn Creek, the majority of proposed improvements would take place within the existing development footprint of the WWTF.

This BRA has been prepared as an appendix to an Initial Study (IS) being prepared for the Proposed Project in accordance with CEQA and the California Clean Water State Revolving Fund Program requirements.

2.0 REGULATORY OVERVIEW 2.1 FEDERAL Endangered Species Act The U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) are agencies responsible for implementing the federal Endangered Species Act (ESA) of 1973 (16 USC Section 1531 et seq.). Under the ESA, threatened and endangered species on the federal list and their habitats (50 CFR Subsection 17.11, 17.12) are protected from “take” (i.e., activities that harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect) as well as any attempt to engage in any such conduct, unless a Section 10 permit is granted to an individual or a Section 7 consultation and a Biological Opinion with incidental take provisions are provided to a lead federal agency. Pursuant to the requirements of the ESA, an agency reviewing a proposed project within its jurisdiction must determine whether any federally listed species may be present within the study area and vicinity and determine whether the proposed project will have a potentially significant impact upon such species. Under the ESA, habitat loss is considered to be an impact to the species. In addition, the agency is required to determine whether the project is likely to jeopardize the continued existence of any species proposed to be listed under the ESA or result in the destruction or adverse modification of critical habitat proposed to be designated for such species (16 USC Section 1536[3], [4]). Therefore, project-related impacts to these species, or their habitats, would be considered significant and require mitigation.

Under the ESA, critical habitat may be designated by the Secretary of the Interior for any listed species. The term "critical habitat" for a threatened or endangered species refers to the following: specific areas within the geographical range of the species at the time it is listed that contain suitable habitat for the species, which may require special management considerations or protection; and specific areas outside the geographical range of the species at the time it is listed that contain suitable habitat for the species and is determined to be essential for the conservation of the species. Under Section 7 of the ESA, all federal agencies (including the USFWS and NMFS) are required to ensure that any action they authorize, fund, or carry out will not likely jeopardize the continued existence of a listed species or modify their critical habitat.

Migratory Bird Treaty Act Most bird species, especially those that are breeding, migrating, or of limited distribution, are protected under federal and/or State regulations. Under the Migratory Bird Treaty Act (MBTA) of 1918 (16 USC Subsection 703-712), migratory bird species, their nests, and their eggs are protected from injury or death, and any project-related disturbances during the nesting season. As such, project-related disturbances must be reduced or eliminated during migratory bird nesting activities.

Analytical Environmental Services 6 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment Wetlands and Waters of the U.S. The U.S. Army Corps of Engineers (USACE) has primary federal responsibility for administering regulations that concern waters of the U.S. (including wetlands), under Section 404 of the Clean Water Act (CWA). Section 404 of the CWA regulates the discharge of dredged or fill material into waters of the U.S. The USACE requires that a permit be obtained if a project proposes the placement of structures within, over, or under navigable waters and/or discharging dredged or fill material into waters below the ordinary high water mark (OHWM). The USACE has established a series of nationwide permits (NWP) that authorize certain activities in waters of the U.S.

In addition, a Section 401 Water Quality Certification Permit is required to comply with CWA Sections 301, 302, 303, 306, and 307 and has been delegated by EPA to the Regional Water Quality Control Board (RWQCB). Anyone that proposes to conduct a project that may result in a discharge to U.S. surface waters and/or “waters of the state” including wetlands (all types) year round and seasonal streams, lakes, and all other surface waters would require a federal permit. At a minimum, any beneficial uses lost must be replaced by a mitigation project of at least equal function, value, and area. Waste Discharge Requirements Permits also required pursuant to California Water Code Section 13260 for any persons discharging or proposing to discharge waste, including dredge/fill, that could affect the quality of the waters of the state. The RWQCB addresses both the federal and State requirements in the issuance of a discharge permit.

2.2 STATE California Endangered Species Act The California Endangered Species Act (CESA) prohibits the take of State-listed threatened and endangered species. Under the CESA, State agencies are required to consult with the California Department of Fish and Wildlife (CDFW) when preparing CEQA documents. Under the CESA, the CDFW is responsible for maintaining a list of rare, threatened, and endangered species designated under State law (California Fish and Game Code 2070-2079). The CDFW also maintains lists of candidate species, species of special concern, and fully protected species. Candidate species are those taxa which have been formally recognized by the CDFW and are under review for addition to the State threatened and endangered list. Species of special concern are those taxa, which are considered sensitive and this list serves as a “watch list”. Pursuant to the requirements of the CESA, agencies reviewing proposed projects within their jurisdictions must determine whether any State-listed species have the potential to occur within a proposed project site and if the proposed project would have any significant impacts upon such species. Project-related impacts to species on the CESA’s rare, threatened, and endangered list would be considered significant and require mitigation. The CDFW can authorize take if an incidental take permit is issued by the Secretary of the Interior or Commerce in compliance with the ESA, or if the director of the CDFW issues a permit under Section 2081 in those cases where it is demonstrated that the impacts are minimized and fully mitigated.

California Environmental Quality Act Section 15380(b) of the CEQA Guidelines provides that a species not listed on the federal or State list of protected species may be considered rare or endangered if the species can be shown to meet certain

Analytical Environmental Services 7 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment specified criteria. Section 15380 defines “endangered” species of plants, fish, or wildlife as those whose survival and reproduction in the wild are in immediate jeopardy and “rare” species as those who are in such low numbers that they could become endangered if their environment worsens. Therefore, a project will normally have a significant effect on the environment if it will substantially affect a rare or endangered species or the habitat of the species. The significance of impacts to a species under CEQA must be based on analyzing actual rarity and threat of extinction despite legal status or lack thereof.

California Fish and Game Codes The California Fish and Game Code defines take (Section 86) and prohibits taking of a species listed as threatened or endangered under the CESA (California Fish and Game Code Section 2080), or otherwise fully protected (California Fish and Game Code Sections §3511, §4700, §5050, and §5515). Section 2081(b) and (c) of the CESA allows the CDFW to issue an incidental take permit for a State listed threatened and endangered species if specific criteria outlined in Title 14 CCR, Sections 783.4(a), (b) and California Fish and Game Code Section 2081(b) are met. The California Fish and Game Code Section 3503 states that it is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by the code. Section 3503.5 states that it is unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird. Section 3513 states that it is unlawful to take or possess any migratory nongame bird as designated in the MBTA or any part of such migratory nongame bird except as provided by rules and regulations adopted by the Secretary of the Interior under provisions of the MBTA. If a project is planned in an area where a species or specified bird occurs, an applicant must design the project to avoid all take of non-listed migratory birds; the CDFW cannot provide take authorization under the CESA. The CDFW protects plants designated as endangered or rare under Fish and Game Code Section 1900.

California Fish and Game Code Sections 1600-1619 regulate impacts to State waters and stream and lake beds. Section 1602 requires notification before beginning any activity that may obstruct or divert the natural flow of a river, stream, or lake; change or use any material from the bed, channel, or bank of a river, stream, or lake; or deposit or dispose of debris, waste, or other material containing crumbled, flaked, or ground pavement where it can pass into a river, stream, or lake. California Fish and Game Code Section 1602 applies to all perennial, intermittent, and ephemeral rivers, streams, and lakes in the state. Notification of the CDFW will be required prior to installation of the proposed outfall. The City and the CDFW must enter into an agreement prior to such any action which will result in such an impact.

2.3 LOCAL City of Shasta Lake General Plan (1999) and Amendments The City of Shasta Lake General Plan (General Plan) seeks to conserve and manage significant fish, wildlife and vegetation resources in addition to surface and groundwater resources.

The following General Plan guiding and implementation policies associated with biological resources are applicable to the Proposed Project.

Analytical Environmental Services 8 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment Guiding Policies W-a This City shall maintain standards for erosion and sediment control plans for development.

W-b Septic systems, waste disposal sites, and other sources of hazardous or polluting materials shall be designed to prevent contamination to rivers, creeks, streams, reservoirs, or the groundwater basin in accordance with standards accepted by or imposed by the City, Shasta County Environmental Health Division and the State Regional Water Quality Control Board.

FW-b Projects that may impact rare, threatened or endangered plant or species, as officially designated by federal and State resource agencies, shall be designed or conditioned to avoid significant adverse impacts on those species.

3.0 METHODOLOGY 3.1 PRELIMINARY DATA GATHERING AND LITERATURE REVIEW Prior to conducting the biological surveys, Analytical Environmental Services (AES) obtained biological information for the study area from the following sources:

Analytical Environmental Services 9 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment 3.2 FIELD SURVEYS The 106-acre study area for this BRA includes the WWTF and associated ponds and reservoirs as well as the reach of Churn Creek which runs east of the property with specific emphases on the area around discharge point 001 and those identified in the separate Biological Assessment/Essential Fish Habitat Assessment Report (AES, 2014b; Appendix E of Initial Study). General biological surveys, botanical inventory survey, arborist inventory, essential fish habitat assessment, and a California red-legged frog (Rana draytonii) site assessment were conducted within the study area between March 27 and May 28, 2014. General biological surveys were conducted on March 27 and May 2, 2014. The botanical inventory survey, arborist survey, and wetland delineation were conducted within the study area on May 2, 2014. The essential fish habitat assessment and a California red-legged frog site assessment were conducted on March 27, and May 27-28, 2014.

The botanical surveys consisted of conducting a floristic inventory, in accordance with CDFW’s (2009) plant survey protocols. The general biological surveys consisted of evaluating biological communities and documenting potential habitat for special status species with the potential to occur within the study area. Plants observed within the study area are identified in Attachment 2.

The habitat types were classified using the Manual of California Vegetation, Second Edition (MCV; Sawyer et al, 2009) and were modified based on existing habitat conditions within the study area. Wetlands and other aquatic habitats within the study area were identified based on the wetland features mapped on the NWI map (USFWS, 2007). Wetland features were mapped within the WWTF site using criteria defined in the 1987 Wetland Delineation Manual by the USACE and the Regional Supplement for the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (USFWS, 2008).

4.0 ENVIRONMENTAL SETTING 4.1 CLIMATE The Sacramento Valley-Shasta College (Station #224) climate data obtained in the vicinity of the study area documented an average total annual precipitation of 8.68 inches for the April 2013 to March 2014 water year (CIMIS, 2014). The Shasta Dam (Station #048135) monthly record climate data recorded an average total annual precipitation of 61.82 inches from January 1943 to March 2013 (WRCC, 2014). Therefore, the average precipitation obtained for the 2013 through 2014 water year is approximately 14 percent of the average total annual precipitation documented over the last 70 years.

4.2 SOIL TYPES The study area is comprised of the following three soil types: (AnD) Auburn loam, 8 to 30 percent slopes, (BkC) Boomer gravelly loam, 0 to 15 percent slopes, and (AtE2) Auburn Very Stony Clay Loam, 30 to 50 Percent Slopes (NRCS, 2014). None of these soils are considered hydric (NRCS, 2014). A soils map of the study area is provided in Figure 5. The soil types are described in detail below.

Depth to water table is more than 80 inches. Depth to restrictive feature is 45 to 49 inches to paralithic bedrock. The soil type is well drained with a very low to moderately low capacity of the most limiting layer to transmit water. The soil profile is typically gravelly loam from 0 to 3 inches, gravelly sandy clay loam from 3 to 23 inches, clay loam from 23 to 45 inches, and weathered bedrock from 45 to 49 inches (NRCS, 2014).

Auburn Loam, 8 to 30 Percent Slopes (AnD) This soil type is found on the backslope and shoulder landforms of the mountain flank with parent material from residuum weathered from metavolcanics. Depth to water table is more than 80 inches. Depth to restrictive feature is from 24 to 28 inches to paralithic bedrock. The soil type is well drained with a very low to moderately low capacity of the most limiting layer to transmit water. The soil profile is typically loam from 0 to 8 inches, gravelly loam from 8 to 24 inches, and unweathered bedrock from 24 to 28 inches (NRCS, 2014).

Auburn Very Stony Clay Loam, 30 to 50 Percent Slopes (AtE2) This soil type is found on the backslope and mountainflank landforms of the mountain landform with parent material from residuum weathered from metavolcanics. Depth to water table is more than 80 inches. Depth to restrictive feature is from 27 to 31 inches to paralithic bedrock. The soil type is well drained with a low to moderately low capacity of the most limiting layer to transmit water. The soil profile is typically slightly acid, very stony clay loam from 0 to 5 inches, slightly acid, gravelly clay loam from 5 to 27 inches, and unweathered bedrock from 27 to 31 inches (NRCS, 2014).

4.3 VEGETATION COMMUNITIES AND WILDLIFE Vegetation communities (assemblages of plant species growing in an area of similar biological and environmental factors) in upland habitats were classified using the CDFW Terrestrial Natural Communities of California system, or “Holland type” (Holland, 1986), and where applicable, detailed by "Vegetation Series" (distinctive associations of plants, described by dominant species and particular environmental setting) using the CNPS Vegetation Classification system (Sawyer and Keeler-Wolf, 1995). Wetlands and other aquatic habitats were classified using the USFWS National Wetlands Inventory Classification System for Wetland and Deepwater Habitats, or “Cowardin class” (Cowardin et al., 1979).

The study area is located in an urbanized setting surrounded primarily by residential/industrial development. There are six different land cover types in the study area for the WWTF site: ruderal/developed, riparian, oak woodland, disturbed oak savanna, perennial stream, and man-made drainage ditch. Representative photographs of the habitat types within the study area are shown in Figure 6. A habitat map is provided as Figure 7. Wetland features and waters of the U.S. are shown in Figure 8. Dominant vegetation occurring within each land cover type is described in further detail below.

The majority of the study area consists of disturbed habitat and does not provide high wildlife value due to nearby traffic on surrounding roadways and the high level of human activity associated with proximity to

The majority of the project area lacks the quality of habitat needed to support diverse wildlife populations and their use; however, wildlife species that are tolerant of high levels of human disturbance may utilize the study area for foraging and cover. Several bird species were observed in the study area including black phoebe (Sayornis nigricans), killdeer (Charadrius vociferous), American crow (Corvus brachyrhynchos), house sparrow (Passer domesticus), mourning dove (Zenaida macroura), mallard duck (Anas platyrhynchos), and Canadian goose (Branta Canadensis). Small mammals such as California ground squirrel (Spermophilus beecheyi) were observed in the study area. Other small mammals including vole (Microtus spp.), opossum (Didelphis virginiana), and raccoon (Procyon lotor) are expected to live in and use the study area for a dispersal corridor.

5.0 RESULTS 5.1 HABITAT TYPES Terrestrial habitat types within the study area include ruderal/developed areas, riparian, oak woodland and disturbed oak savanna. Aquatic habitats within the study area include man-made reservoirs, man- made ditches, irrigated wetland-like formations, and stream courses. A general discussion of each habitat type is provided below. Table 1 summarizes the acreages of habitat types within the study area.

5.1.1 Terrestrial Habitats within the Study Area Ruderal/Disturbed The majority of the study area is comprised of ruderal/developed areas. These areas include paved and graded roads and road shoulders within the WWTF site and along Tibbitts Road that extends east from Ashby Road through the WWTF site, infrastructure associated with the WWTF site, ornamental

Analytical Environmental Services 17 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment landscaping, and human-disturbed areas associated with earth-moving activities. Dominant weedy vegetation associated with this habitat type includes ripgut brome (Bromus diandrus), soft chess brome (Bromus hordeaceus), winter vetch (Vicia villosa), prickly lettuce (Lactuca serriola), common sowthistle (Sonchus oleraceus), short-pod mustard (Hirschfeldia incana), wild oat (Avena fatua), and rough cat’s ear (Hypochaeris radicata). Ornamental landscaping vegetation includes American sweetgum (Liquidamber stryraciflua), palm (Washingtonia sp.), and California redwood (Sequioa sempervirens).

Riparian Riparian habitat occurs along the perennial reaches of Churn Creek within the east and south portions of the study area. This habitat type consists primarily of an overstory of valley oak (Quercus lobata), arroyo willow (Salix lasiolepis), Goodding’s willow (Salix gooddingii), and white alder (Alnus rhombifolia). Understory and herbaceous species include California rose (Rosa californica), narrow-leaved willow (Salix exigua), California coffeeberry (Rhamnus californica), western poison oak (Toxicodendron diversilobum), Himalayan blackberry (Rubus discolor), toad rush ( bufonius), soft rush (Juncus effuses), spreading rush (Juncus patens), tall flatsedge (Cyperus eragrostis), and sedge (Carex sp.). To a lesser extent similar riparian habitat exists along the two unnamed tributaries which flow through the southern portion of the study area.

Oak Woodland Oak woodland occurs in the east areas of the study area and on both sides of Churn Creek. Dominant overstory vegetation includes blue oak (Quercus douglasii), valley oak, and interior live oak (Quercus wislizenii), with scattered California buckeye (Aesculus californica) and foothill pine (Pinus sabiniana) dispersed throughout. The understory vegetation varies in density and is relatively thin with little understory. Intermittently dense understory shrub vegetation occurs in other areas associated with rock outcroppings. Understory vegetation includes western poison oak, California coffeeberry, and buckbrush (Ceanothus cuneatus).

Disturbed Oak Savanna Disturbed oak savanna habitat occurs in the eastern portions of the study area. This land cover type includes sparse vegetation previously described for the ruderal/disturbed areas and oak woodland habitat within the study area. A spray field irrigation system for the disposal of treated effluent has been installed by trenching below ground and is currently operated throughout the disturbed oak savanna habitat type. This area is also actively used as pasture land for cattle grazing.

5.1.2 Aquatic Habitats within the Study Area Treatment Basins and Reservoir Five man-made basins and one 400 acre-foot (af) reclaimed reservoir exist within the ruderal/developed habitat within study area and serve as seasonal and intermittent storage for intermediate stages of wastewater treatment. The unlined basins are man-made, engineered, and constructed fully in uplands. Dominant obligate and/or facultative vegetation observed in the basins include prickly lettuce (Lactuca serriola), rough cocklebur (Xanthium strumarium), Italian ryegrass (Lolium multiflorum), and curly dock ( crispus).

Analytical Environmental Services 18 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment The 400-af reclaimed reservoir is located in the western portion of the study area. The reservoir is lined with natural clay and is used for temporary storage of tertiary treated recycled water. During the time when the WWTF cannot discharge to Churn Creek, recycled water from the reservoir is used to supply the WWTF’s reclamation accounts or is disposed of via sprayfield irrigation. During the winter, the treated water can be discharged to Churn Creek via discharge point 002 in accordance with the NPDES permit. The reservoir itself does not exhibit significant aquatic vegetation. The reservoir currently experiences regular changes in volume based on the reclaimed water storage needs, including holding water during the wet months when irrigation rates and recycled water demands are low.

Man-made Ditches Several manmade roadside ditches occur within the study area. Features observed along the bed and banks of the man-made ditches include defined bed and banks that range between approximately one- and 1.5-feet wide, a clearly defined OHWM, and distinct drainage patterns. Although hydric soils necessary to meet the criteria of wetland features are not present, the features are considered ditches because they contain defined beds and banks in accordance with the USACE regulations identified in 33 CFR Part 328. The man-made ditches receive water via direct precipitation during rain events and from runoff from unnamed graded access roads within the WWTF property, and adjacent nonnative grassland and agricultural areas. The ditches were excavated wholly in and drain only uplands and do not carry a relatively permanent flow of water. Water from the ditches is culverted under roadways and drains over land to Churn Creek, which flows southeast of the property.

Stream Courses A perennial stream, Churn Creek and some reaches of unnamed tributaries, occurs within the study area. Churn Creek is a perennial blue line stream that runs east and south of the WWTF. During the summer months when there is little rainfall, Churn Creek flows often run low in its lower reaches, occasionally causing ponding of standing water to occur within the creekbed. Dominant vegetation associated with this perennial stream is identical to those described within the riparian habitat above. The two unnamed tributaries are also bordered by the riparian habitat description above. The cobble-reinforced discharge channel which drains the reclaimed reservoir in the winter months flows into the natural water course of the northern unnamed channel. This cobble-reinforced channel shows developed riparian vegetation including blackberries and willows, but is otherwise marginal due to variable intermittent flows and restricted stream habitat diversity. Below the cobble reinforced area is a significant riparian area. The tributary which originates offsite has a more consistent flow pattern but is still intermittent in nature. Downstream from where these unnamed tributaries merge, there is a small check dam which collects any runoff from the spray fields in the summer to prevent runoff from reaching Churn Creek. This small check dam overtops during the time when water from the reclaimed reservoir is discharged through the pump station into the upper cobble-lined channel in accordance with the WTTF’s NPDES permit. Discharge point 002 is the location of where these tributaries enter Churn Creek.

Irrigated Wetland-like Features Several man-made irrigated wetland-like features were observed to occur throughout the disturbed oak savanna habitat and treated effluent sprayfields located along the eastern perimeter of the study area . These wetland-like features have formed solely as a result of WWTF standard operations, including spray

Analytical Environmental Services 19 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment field irrigation and from leaks in the effluent pipeline that connects to the discharge point 001 outfall in Churn Creek.

During surveys, pooling irrigation water was observed in the immediate vicinity of some of the sprinklers within the spray fields. Hydrophytic vegetation typical of disturbed wet areas is growing sparsely in areas where spraying has been relatively concentrated. Vegetation observed in these areas primarily consisted of curly dock (Rumex crispus), water smartweed (Polygonum coccineum), mannagrass (Glyceria sp.), and water speedwell (Veronica anagallis-aquatica). Due to the sloped topography of the site and well drained soils, standing water would not naturally form long enough to facilitate wetland creation in these areas without WWTF-associated activity.

Further, neither sufficient hydric vegetation nor hydric soils were observed within the wet areas. Wetland hydrology indicators including visible irrigation water, saturation, and visible inundation are present as a result of WWTF standard operations and procedures including utilization of spray fields. Based on the three-parameter test, the absence of hydric soil indicators and sufficient hydrophytic vegetation indicates these features do not constitute a wetland.

SPECIAL STATUS SPECIES For the purposes of this assessment, special status has been defined to include those species that are:

. Listed as endangered or threatened under the ESA (or formally proposed for, or candidates for, listing); . Listed as endangered or threatened under the CESA (or proposed for listing); . Designated as endangered or rare, pursuant to California Fish and Game Code (§1901); . Designated as fully protected, pursuant to California Fish and Game Code (§3511, §4700, or §5050); . Designated as species of concern by the CDFW (CEQA Guidelines Section 15380); or, . Defined as rare or endangered under CEQA.

Table 2 summarizes the regionally occurring special status species identified on the USFWS, CNPS, and the CNDDB lists and provides a rationale as to whether the species have the potential to occur within the study area. Presence of the species or their habitat was evaluated during the biological surveys. Species without the potential to occur in the vicinity of the study area are not discussed further in this section. Special status species with the potential to occur within the study area are discussed below, including distances from the study area to reported CNDDB occurrences (CDFW, 2003). USFWS, CNDDB, and CNPS lists are provided in Attachment 1.

Amphibians Foothill yellow-legged frog (Rana boylii) Federal Status – None State Status – Species of Concern

Foothill yellow-legged frogs occur in suitable habitat throughout California. Suitable habitat consists of shallow, flowing freshwater in moderate sized streams with some cobble substrate. Foothill yellow-legged frogs utilize streams and rivers with rocky substrate and open banks in forest, chaparall, and woodland habitats. They are occasionally found in isolated pools, backwaters with substantial vegetation, and deep, shaded spring-fed pools. Suitable habitat ranges from sea level to 6,700 feet (2,040 meters).

The USFWS has not published a recovery plan or designated critical habitat for the Foothill yellow-legged frog. An Animal Candidate Review for Listing as Endangered or Threatened Species was completed for the Foothill yellow-legged frog in November of 1991 and 1994. The species is currently under review.

There are 5 CNDDB records for this species within 5 miles of the study area. All 5 records of the Foothill yellow-legged frog are located immediately adjacent to the Sacramento River. There are no recorded occurrences of Foothill yellow-legged frogs within the Churn Creek tributary of the Sacramento River within 5 miles of the study area. The nearest record is approximately 3.5 miles southwest of the study area adjacent to the Sacramento River (CNDDB occurrence: 460). The record is dated June 4, 2005 and states that the occurrence is presumed extant.

The riparian woodland surrounding Churn Creek and oak woodland could potentially provide upland refugia and dispersal habitat for Foothill yellow-legged frogs. Foothill yellow-legged frogs are not likely to occur in the man-made reservoirs due to the absence of significant aquatic vegetation. The reservoirs also experience regular changes in volume based on the storage needs and releases performed under standard WWTF operations, which yields the reservoirs further unsuitable for use by Foothill yellow- legged frogs. Similarly, the wetland-like formations do not meet Foothill yellow-legged frogs breeding habitat requirements due to variable intermittent flows, inundation that does not persist for a sufficient portion of the breeding season. Churn Creek provides potential breeding habitat for Foothill yellow- legged frogs due to its dense, emergent vegetation, and water depth that persists for a sufficient portion of the breeding season. However, the presence of predators such as bullfrogs, decreases the quality of habitat. Bullfrog tadpoles were observed throughout the study area within Churn Creek during the site assessment conducted by AES on May 2, 2014.

This species was not observed in the study area and the only occurrences of this species within 5 miles of the study area were located immediately adjacent to the Sacramento River. Due to the ruderally developed characteristics of the aquatic resources found on the subject property and the marginal habitat quality of these resources, combined with the lack of documented historic population use, it is determined that study area would not support Foothill yellow-legged frogs.

Analytical Environmental Services 29 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment California Red-Legged Frog (Rana aurora draytonii; CRLF) Federal Status – Threatened State Status – California Species of Concern

The California red-legged frog (CRLF) requires aquatic breeding areas embedded within a matrix of riparian and upland dispersal habitats. Breeding aquatic habitats include pools and backwaters within streams, creeks, ponds, marshes, springs, sag ponds, dune ponds, and lagoons. CRLF also breed in artificial impoundments including stock ponds. The breeding period is from November to March. Beginning with the first rains of fall, CRLF may make overland excursions through upland habitats. Most of these overland movements occur at night. CRLF may move distances up to 1.6 kilometers throughout one wet season. CRLF rest and forage in riparian vegetation (USFWS, 2002a). CRLF disperse from their breeding habitat to forage and seek summer habitat if water is not available. Summer habitats include spaces under boulders or rocks and organic debris, such as downed trees or logs; industrial debris; and agricultural features, such as drains, watering troughs, abandoned sheds, or hay-ricks (USFWS, 2002b). CRLF requires 11 to 30 weeks of permanent water for larval development (CDFW, 2003).

On May 28, 2002, the USFWS published a recovery plan for the CRLF throughout California. The objective of the recovery plan is to reduce any threats to the species and to improve the status of the CRLF populations sufficiently to warrant delisting. In this recovery plan, 35 Core Areas have been designated within eight recovery unit boundaries for CRLF (USFWS, 2002b). Recovery units are “regions of the species’ distribution that are distinct from one another based on ecological characteristics, status of the species, threats to the continued existence of the species, or recovery actions needed within the area.” Core Areas are “watersheds, or portions thereof, that have been determined to be essential to the recovery of the CRLF.” Core Areas have no legal mandate for protection under the ESA and solely rely upon voluntary implementation. The study area does not occur within any of the Core Areas of the Recovery Unit Boundary. The USFWS revised the critical habitat designated for CRLF on March 17, 2010 (USFWS, 2010a). The study area does not occur within designated critical habitat for this species.

There are no CNDDB occurrences documented for CRLF within the 5-mile radius of the study area;. No CNDDB occurrences have been recorded on the Shasta Dam quad or eight surrounding quads. The study area occurs outside of the current known geographic range for this species as it does not occur within any of the Core Areas of the Sierra Nevada Foothills and Central Valley Recovery Unit Boundary or within designated critical habitat for CRLF.

The riparian woodland surrounding Churn Creek and oak woodland could potentially provide upland refugia and dispersal habitat for CRLF. CRLF are not likely to occur in the man-made reservoirs due to the absence of significant aquatic vegetation. The reservoirs also experience regular changes in volume based on the storage needs and releases performed under standard WWTF operations, which yields the reservoirs further unsuitable for use by CRLF. Similarly, the wetland-like formations do not meet CRLF breeding habitat requirements due to variable intermittent flows, water depth less than 2 1/3-feet deep, and inundation that does not persist for a sufficient portion of the breeding season. Churn Creek provides potential breeding habitat for CRLF due to its dense, emergent vegetation, and water depth greater than 2 1/3-feet deep that persists for a sufficient portion of the breeding season. However, the presence of

Analytical Environmental Services 30 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment predators such as bullfrogs, decreases the quality of habitat. Bullfrog tadpoles were observed throughout the study area within Churn Creek during the site assessment conducted by AES on May 2, 2014.

This species was not observed in the study area. Additional information pertaining to the suitability of available habitat for CRLF within the study area can be found in the separate CRLF Site Assessment Report prepared by AES for the City of Shasta Lake. Due to the ruderally developed characteristics of the aquatic resources found on the subject property and the marginal habitat quality of these resources, combined with the lack of documented historic population use, it is determined that study area would not support CRLF.

Reptiles Western pond turtle (Emys marmorata; WPT) Federal Status – None State Status – Species of Concern

Western pond turtles (WPT) require terrestrial and aquatic habitats. They are found along ponds, marshes, rivers, streams, and irrigation ditches with abundant aquatic vegetation (Jennings, 2000; Reese and Welsh, 1997). WPT requires aquatic habitats with suitable basking sites. Nest sites are most often characterized as having gentle slopes less than 15 percent with little vegetation or sandy banks. WPT are found from zero to 1,430 meters above sea level (Stebbins, 2003). WPT prefers pools with rocky or muddy bottoms in woodland, forest, or grassland areas. During summer droughts, WPT aestivate in burrows in soft bottom mud (The Center for North American Herpetology, 2014). The period of identification for WPT is March through October. WPT are known throughout California west of the Sierra-Cascade crest, and are absent from desert regions except along the Mohave River and its tributaries (Stebbins, 2003).

There are 5 CNDDB records for western pond turtles within 5 miles of the study area. The nearest records are located approximately 1.3 miles northeast of the study area from March 29, 2007 (CNDDB occurrence number: 656). The record states that the occurrence is presumed extant. The study area provides moderately suitable terrestrial habitat within the riparian woodland and oak woodland habitats in the vicinity of aquatic resources in the study area. The study area provides marginally suitable habitat for the western pond turtle within the man-made aquatic resources including the cobble-reinforced outflow channel, the reservoirs, and Churn Creek. WPT are not likely to occur in the man-made reservoirs due to the absence of significant aquatic vegetation. The reservoirs also experience regular changes in volume based on the storage needs and releases performed under standard WWTF operations, which yields the reservoirs further unsuitable for use by WPT. Churn Creek provides potential habitat for WPT due to its dense, emergent vegetation, available basking sites, and perennial flows.

WPT were not observed during the surveys conducted between March and May of 2014. Due to the ruderally developed characteristics of the aquatic resources found on the subject property, the site only provides marginally suitable habitat. Therefore, it is possible, but unlikely for WPT to occur In the vicinity of Churn Creek, including the portion of Churn Creek that runs adjacent to the study area.

Analytical Environmental Services 31 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment Migratory Birds and Birds of Prey California Fish and Game Code 3503.5 protects all birds in the orders Falconiformes and Strigiformes (collectively known as birds of prey). Migratory birds and other birds of prey have the potential to nest in the and trees within the disturbed, riparian, and oak woodland habitats of the study area. As discussed previously, several birds were observed within the study area during biological surveys including black phoebe (Sayornis nigricans), killdeer (Charadrius vociferous), American crow (Corvus brachyrhynchos), house sparrow (Passer domesticus), and mourning dove (Zenaida macroura). Although suitable habitat is present, no migratory birds or birds of prey that would be protected by California Fish and Game Code 3503.5 were observed within or in the vicinity of the study area during biological surveys conducted by AES.

6.0 IMPACTS AND MITIGATION MEASURES 6.1 SENSITIVE HABITAT IMPACTS Sensitive habitats include those that are of special concern to resource agencies or those that are protected under CEQA, Section 1600 of the California Fish and Game Code, or Section 404 of the CWA. Additionally, sensitive habitats are protected under the specific policies outlined in the City of Shasta Lake General Plan. Sensitive habitats within the study area include Churn Creek, riparian habitat, oak savanna and oak woodland (Figure 7). Impacts to Churn Creek and riparian habitat are discussed further within the Waters of the U.S. section below. The majority of construction activities associated with the Proposed Project will take place within the previously disturbed footprint of the WWTF. While use of sprayfields would cease as a result of the Proposed Project, the irrigation infrastructure would be abandoned in place, so there would be no potential effects to the disturbed oak savanna habitat type. The elimination of irrigation activities would allow this habitat type to return to its more natural state. As the ruderal/developed areas within the WWTP do not provide quality habitat for native plants and wildlife that USFWS and CDFW consider sensitive, this impact is considered less than significant. No mitigation is recommended.

6.2 WATERS OF THE U.S. A wetland delineation was conducted for the study area and has been submitted to the USACE for verification (AES, 2014c; Appendix F of Initial Study). The results are considered preliminary until the USACE verifies the findings. The majority of construction activities associated with the Proposed Project will take place within the previously disturbed footprint of the WWTF. While use of sprayfields would cease as a result of the Proposed Project, the irrigation infrastructure would be abandoned in place, so there would be no potential effects to the unnamed tributaries that occur in the southern portion of the study area. Similarly, the 400-acre foot seasonal storage reservoir would be abandoned in place. However, construction of the new effluent discharge pipeline and outfall structure will result in impacts to riparian habitat and impacts within the bed bank and channel of Churn Creek, a jurisdictional waters of the U.S. Prior to construction, the City shall obtain a permit from the USACE in accordance with Section 404 of the CWA, a 401 Water Quality Certification from the CVRWQCB and a Section 1602 Streambed Alteration Agreement (SAA) from CDFW. All conditions of the permits shall be adhered to. Final mitigation requirements and habitat restoration/replacement ratios will be identified as a condition of the USACE 404 Permit and SAA obtained from the CDFW. At minimum, as a requirement of permits, the

Analytical Environmental Services 32 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment City would be required to replace lost habitat be restoring the riparian vegetation impacted during construction activities at a 1:1 ratio (meaning that one acre will be restored for every one acre impacted). Additionally, the City shall comply with the State’s NPDES General Construction Permit issued by the RWQCB and prepare a Stormwater Pollution Prevention Plan (SWPPP). Implementation of the SWPPP will ensure that measures are in place to prevent water quality effects in Churn Creek.

6.3 TREES The Proposed Project has the potential to impact trees in the vicinity of Churn Creek. Construction activities associated with the replacement of the existing effluent discharge pipeline may require the removal of trees. Trees in the vicinity of Churn Creek that have the potential to be impacted by the Proposed Project have been inventoried and are discussed in further detail in the separate Arborist Report prepared by AES for the City. In the event that the removal of existing trees is required, mitigation measures are also provided in the Arborist Report (AES, 2014a; Appendix H of Initial Study).

6.4 SPECIAL STATUS PLANTS A focused botanical survey was conducted within the study area during the appropriate bloom period all special status plant species with the potential to occur in the study area. No special status plants were observed during the focused botanical surveys of the study area; therefore, special status plants do not occur in the study area and would not be impacted by the Proposed Project. No mitigation is required.

6.5 SPECIAL STATUS WILDLIFE Fish The Proposed Project has the potential to result in impacts to special status fish species as a result of construction activities in the vicinity of Churn Creek and the discharge from the Proposed Project. As a direct tributary to the Sacramento River, Churn Creek provides potentially suitable habitat for Central Valley steelhead, and various runs of Chinook salmon. Impacts that have the potential to occur to these species as a result of the Proposed Project are analyzed in the separate Biological Assessment/Essential Fish Habitat Assessment Report (AES, 2014b; Appendix E of Initial Study). The analysis shows that the expected flow increase due to increased discharge from the WWTF and location of the outfall would not adversely impact to salmonid habitat in Churn Creek. Additionally, the City shall comply with the State’s NPDES General Construction Permit issued by the RWQCB and prepare a SWPPP. Implementation of the SWPPP will ensure that measures are in place to prevent temporary water quality effects from construction that could affect fish habitat in Churn Creek. No further mitigation is required.

Reptiles The Proposed Project has the potential to impact the western pond turtle within the riparian habitat, adjacent to Churn Creek. The following mitigation measures are recommended to avoid impacts to western pond turtles:

. A qualified biologist shall conduct a preconstruction survey within 14 days prior to commencement of construction activities anticipated to occur within 100 feet from riparian

Analytical Environmental Services 33 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment vegetation surrounding Churn Creek. A report shall be submitted to the City to document the reports of the preconstruction survey. . Prior to commencement of any groundbreaking activities, all construction personnel will receive training on identification of western pond turtle and procedures to be implemented in the event that western pond turtle is encountered during construction activities. . Prior to commencement of daily construction activities within a 100-foot buffer of riparian vegetation surrounding Churn Creek, a qualified biologist will conduct two preconstruction surveys for WPT. The first survey shall be conducted within 14 days prior to construction, and the second survey will be conducted within 24 hours prior to construction. If WPT is present, the qualified biologist will be allowed sufficient time to move the species from the work site before work activities begin. . Because WPT may take refuge in cavity-like and den-like structures such as pipes and may enter stored pipes and become trapped, all construction pipes, culverts, or similar structures that are stored at a construction site for one or more overnight periods will be either securely capped prior to storage or thoroughly inspected for these animals before the pipe is subsequently buried, capped, or otherwise used or moved in any way. . In the event that WPT enters a 100 foot buffer of on-going construction activities, a qualified biologist shall be contacted and construction activities shall be placed on hold until the WPT is confirmed to have left the project area or is relocated by a qualified biologist.

Migratory Birds and Other Birds of Prey The Proposed Project has the potential to impact nest sites for federally protected migratory birds within the study area. Construction activities in the vicinity of active nests and any trees anticipated for removal within the oak woodland and riparian vegetation could impact nesting habitat for migratory birds and other birds of prey protected under the MBTA and California Fish and Game Code sections 3503, 3503.5, 3513, and 3511. The following mitigation measures are recommended to avoid impacts to nest sites for migratory birds and other birds of prey:

. For vegetation removal and/or earth-disturbing activities occurring during the nesting season (February 1 through September 1), a qualified biologist shall conduct pre-construction surveys of all potential nesting habitat for all migratory birds within 500 feet of construction activities. The qualified biologist shall document and submit the results of the preconstruction survey in a letter report to the City within 10 days following the survey. If no active nests are identified during the preconstruction survey, then no further mitigation is required provided construction commences within 14 days. . If any active special status bird, migratory bird, or raptor nests are identified during the preconstruction survey within the study area, a no-disturbance buffer zone deemed appropriate to the species will be established around the nests to avoid disturbance or destruction of the nest. The distance around the no-disturbance buffer will be determined by the biologist in coordination with CDFW and will depend on the level of noise or construction activity, the level of ambient noise in the vicinity of the nest, and line-of-sight between the nest and disturbance. These buffers shall be no less than: 1) 500-foot no-disturbance buffer will be created around active raptor nests during the breeding season or until it is determined that all young have fledged, and 2) a 250-100-foot buffer zone will be created around the nests of other migratory or special status

Analytical Environmental Services 34 City of Shasta Lake WWTF Upgrade Project November 2014 Appendix D - Biological Resources Assessment birds and all other birds that are protected by California Fish and Game Code 3503. These buffer zones are consistent with CDFW avoidance guidelines and CDFW buffers required on other similar projects; however, they may be modified in coordination with CDFW based on existing conditions at the project site. A qualified biologist will monitor nests weekly during construction to evaluate potential nesting disturbance by construction activities. The biologist will delineate the buffer zone with construction tape or pin flags until the young have fledged. Guidance from the CDFW will be requested if the nestlings within the active nest appear disturbed. A report shall be prepared and submitted to the City and CDFW following the fledging of the nestlings to document the results. . If vegetation removal activities are delayed or suspended for more than two weeks after the pre- construction survey, the areas will be resurveyed.

Important Information About Your Species List How We Make Species Lists We store information about endangered and threatened species lists by U.S. Geological Survey 7½ minute quads. The United States is divided into these quads, which are about the size of San Francisco.

The animals on your species list are ones that occur within, or may be affected by projects within, the quads covered by the list. Fish and other aquatic species appear on your list if they are in the same watershed as your quad or if water use in your quad might affect them. Amphibians will be on the list for a quad or county if pesticides applied in that area may be carried to their habitat by air currents. Birds are shown regardless of whether they are resident or migratory. Relevant birds on the county list should be considered regardless of whether they appear on a quad list.

Plants Any plants on your list are ones that have actually been observed in the area covered by the list. Plants may exist in an area without ever having been detected there. You can find out what's in the surrounding quads through the California Native Plant Society's online Inventory of Rare and Endangered Plants.

Surveying Some of the species on your list may not be affected by your project. A trained biologist and/or botanist, familiar with the habitat requirements of the species on your list, should determine whether they or habitats suitable for them may be affected by your project. We recommend that your surveys include any proposed and candidate species on your list. See our Protocol and Recovery Permits pages. For plant surveys, we recommend using the Guidelines for Conducting and Reporting Botanical Inventories. The results of your surveys should be published in any environmental documents prepared for your project.

Your Responsibilities Under the Endangered Species Act All animals identified as listed above are fully protected under the Endangered Species Act of 1973, as amended. Section 9 of the Act and its implementing regulations prohibit the take of a federally listed wildlife species. Take is defined by the Act as "to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect" any such animal. Take may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding, or shelter (50 CFR §17.3). http://www.fws.gov/sacramento/es_species/Lists/es_species_lists.cfm 4/6 4/9/2014 Sacramento Fish & Wildlife Office Species List Take incidental to an otherwise lawful activity may be authorized by one of two procedures: If a Federal agency is involved with the permitting, funding, or carrying out of a project that may result in take, then that agency must engage in a formal consultation with the Service. During formal consultation, the Federal agency, the applicant and the Service work together to avoid or minimize the impact on listed species and their habitat. Such consultation would result in a biological opinion by the Service addressing the anticipated effect of the project on listed and proposed species. The opinion may authorize a limited level of incidental take. If no Federal agency is involved with the project, and federally listed species may be taken as part of the project, then you, the applicant, should apply for an incidental take permit. The Service may issue such a permit if you submit a satisfactory conservation plan for the species that would be affected by your project. Should your survey determine that federally listed or proposed species occur in the area and are likely to be affected by the project, we recommend that you work with this office and the California Department of Fish and Game to develop a plan that minimizes the project's direct and indirect impacts to listed species and compensates for project-related loss of habitat. You should include the plan in any environmental documents you file.

Critical Habitat When a species is listed as endangered or threatened, areas of habitat considered essential to its conservation may be designated as critical habitat. These areas may require special management considerations or protection. They provide needed space for growth and normal behavior; food, water, air, light, other nutritional or physiological requirements; cover or shelter; and sites for breeding, reproduction, rearing of offspring, or seed dispersal. Although critical habitat may be designated on private or State lands, activities on these lands are not restricted unless there is Federal involvement in the activities or direct harm to listed wildlife. If any species has proposed or designated critical habitat within a quad, there will be a separate line for this on the species list. Boundary descriptions of the critical habitat may be found in the Federal Register. The information is also reprinted in the Code of Federal Regulations (50 CFR 17.95). See our Map Room page.

Candidate Species We recommend that you address impacts to candidate species. We put plants and animals on our candidate list when we have enough scientific information to eventually propose them for listing as threatened or endangered. By considering these species early in your planning process you may be able to avoid the problems that could develop if one of these candidates was listed before the end of your project.

Species of Concern The Sacramento Fish & Wildlife Office no longer maintains a list of species of concern. However, various other agencies and organizations maintain lists of at-risk species. These lists provide essential information for land management planning and conservation efforts.

Wetlands If your project will impact wetlands, riparian habitat, or other jurisdictional waters as defined by section 404 of the Clean Water Act and/or section 10 of the Rivers and Harbors Act, you will need to obtain a permit from the U.S. Army Corps of Engineers. Impacts to wetland http://www.fws.gov/sacramento/es_species/Lists/es_species_lists.cfm 5/6 4/9/2014 Sacramento Fish & Wildlife Office Species List will need to obtain a permit from the U.S. Army Corps of Engineers. Impacts to wetland habitats require site specific mitigation and monitoring. For questions regarding wetlands, please contact Mark Littlefield of this office at (916) 414-6520.

Updates Our database is constantly updated as species are proposed, listed and delisted. If you address proposed and candidate species in your planning, this should not be a problem. However, we recommend that you get an updated list every 90 days. That would be July 08, 2014.
