Equipment must be checked by a certified mechanic and determined to be running in proper condition before the start of work. Install diesel particulate filters or implement other CARB-verified diesel emission control strategies. Shall not operate a diesel-fueled auxiliary power system (APS) to power a heater, air conditioner, or any ancillary equipment on that vehicle during sleeping or resting in a sleeper berth for greater than 5 minutes at any location when within 100 feet of a restricted areas. To the extent feasible, truck trips shall be scheduled during non-peak hours to reduce perk hour emissions. May 20, 2021  Butte County Department of Development Services   Conditions of Approval – CG Development, Inc. Subdivision TSM20-0001  Page 2 of 11  Operational TAC Emissions  All mobile and stationary Toxic Air Contaminants (TACs) sources shall comply with applicable Airborne Toxic Control Measures (ATCMs) promulgated by the CARB throughout the life of the project (see http:www.arb.ca.gov/toxics/atcm/atcm.htm).  Stationary sources shall comply with applicable District rules and regulations. Fugitive Dust Construction activities can generate fugitive dust that can be a nuisance to local residents and businesses near a construction site. Dust complaints could result in a violation of the District’s “Nuisance” and “Fugitive Dust” Rules 200 and 205, respectively. The following is a list of measures that may be required throughout the duration of the construction activities:  Reduce the amount of the disturbed area where possible.  Use of water trucks or sprinkler systems in sufficient quantities to prevent airborne dust from leaving the site. An adequate water supply source must be identified. Increased watering frequency would be required whenever wind speeds exceed 15 mph. Reclaimed (non-potable) water should be used whenever possible.  All dirt stockpile areas should be sprayed daily as needed, covered, or a District approved alternative method will be used.  Permanent dust control measures identified in the approved project revegetation and landscape plans should be implemented as soon as possible following completion of any soil disturbing activities.  Exposed ground areas that will be reworked at dates greater than one month after initial grading should be sown with a fast-germinating non-invasive grass seed and watered until vegetation is established.  All disturbed soil areas not subject to re-vegetation should be stabilized using approved chemical soil binders, jute netting, or other methods approved in advance by the Butte County Air Quality Management District.  All roadways, driveways, sidewalks, etc. to be paved should be completed as soon as possible. In addition, building pads should be laid as soon as possible after grading unless seeding or soil binders are used.  Vehicle speed for all construction vehicles shall not exceed 15 mph on any unpaved surface at the construction site.  All trucks hauling dirt, sand, soil, or other loose materials are to be covered or should maintain at least two feet of freeboard (minimum vertical distance between top of load and top of trailer) in accordance with local regulations.  Install wheel washers where vehicles enter and exit unpaved roads onto streets, or wash off trucks and equipment leaving the site.  Sweep streets at the end of each day if visible soil material is carried onto adjacent paved roads. Water sweepers with reclaimed water should be used where feasible.  Post a sign in prominent location visible to the public with the telephone numbers of the contractor and the Butte County Air Quality Management District - (530) 332-9400 for any questions or concerns about dust from the project.”  Butte County Department of Development Services   Conditions of Approval – CG Development, Inc. Subdivision TSM20-0001  Page 3 of 11  All fugitive dust mitigation measures required should be shown on grading and building plans. In addition, the contractor or builder should designate a person or persons to monitor the dust control program and to order increased watering, as necessary, to prevent transport of dust offsite. Their duties shall include holidays and weekend period when work may not be in progress. The name and telephone number of such persons shall be provided to the District prior to land use clearance for map recordation and finished grading of the area. Please note that violations of District Regulations are enforceable under the provisions of California Health and Safety Code Section 42400, which provides for civil or criminal penalties of up to $25,000 per violation. Plan Requirements: The note shall be placed on a separate document which is to be recorded concurrently with the final map or on an additional map sheet. This note shall also be placed on all building and site development plans. Timing: Requirements of the condition shall be adhered to throughout all grading and construction periods. Monitoring: The Butte County Department of Development Services and the Public Works Department shall ensure that the note is placed on a separate document which is to be recorded concurrently with the map or on an additional map sheet. Building inspectors shall spot check and shall ensure compliance on-site. Butte County Air Pollution Control District inspectors shall respond to nuisance complaints. 2. Mitigation Measure BIO-1 If the project will include vegetation removal (including grasses) or earthwork of any kind during the nesting season (February 1 through August 31), CDFW recommends a pre- construction nesting bird survey be conducted by a qualified biologist to identify the absence or presence of active (i.e. with eggs or young) nests. The survey area should include the project site and a minimum 300-foot buffer around the project site. To minimize the chance of nests becoming established between the time the survey is conducted and when construction begins, CDFW recommends the preconstruction survey be conducted no more than three (3) days before the start of vegetation removal and/or ground disturbing activities. Please also note that Fish and Game Code section 3503 protects the nests and eggs of all birds, not just migratory birds and birds of prey. If active nests are observed during the pre-construction survey a species-appropriate no-disturbance buffer should be established to protect the active nest. Nesting birds’ tolerance of disturbance varies greatly depending on species, intensity of disturbance, whether the nesting pair is accustomed to disturbance, the location of the nest, the stage of development of nestlings, etc. Disturbance too close to the nest may impact the parents’ ability to forage effectively and reduce nestlings’ chances of survival. In some cases, disturbance can cause the parents to abandon the nest completely. For these reasons the size of the no-disturbance buffer should be determined by the qualified biologist. CDFW is available to provide comments and feedback on nesting bird avoidance strategies if desired. However, it should be noted that CDFW cannot guarantee that any specific buffer width will be sufficient to completely avoid take in any given situation, and therefore CDFW cannot approve or disapprove specific buffer proposals. Plan Requirements: Perform protocol-level surveys for migratory birds protected by the California Department Fish & Game Code and the Migratory Bird Treaty Act. This measure shall be recorded on an additional map sheet to the Parcel Map.  Butte County Department of Development Services   Conditions of Approval – CG Development, Inc. Subdivision TSM20-0001  Page 4 of 11  Timing: Requirements of the condition shall be adhered to prior to and during construction activities planned to occur during nesting seasons for CDFC and MBTA species (between February 1 and August 31). Monitoring: The Butte County Department of Development Services and the Public Works Department shall ensure that the note is recorded an additional map sheet of the Parcel Map. Department of Development Services shall ensure the condition is met at the time of construction activities. 3. Mitigation Measure BIO-2 If the existing structure within the project is slated for removal and/or demolition, then CDFW recommends a survey for roosting bats be conducted within 10 days prior to the proposed demolition. Surveys for day roosting bats should be conducted by a qualified bat biologist. The survey should include a minimum of one daytime survey to evaluate potential roost sites within the structures and one emergence survey to determine the absence or presence of bats. The bat maternity season is roughly defined as April 1 through August 31. Exclusion of day roosting bats should not be performed during the bat maternity season. If day and/or maternity roosts are observed CDFW is available to provide comments and feedback on roosting bat avoidance and minimization strategies. CDFW may recommend minimization measures such as the creation of alternative roost sites if the loss of maternity and/or day roosting habitat is unavoidable. Plan Requirements: Survey shall be conducted 10 days prior to removal and/or demolition. This measure shall be recorded on an additional map sheet to the Parcel Map. Timing: Requirements of the condition shall be adhered to removal and/or demolition. Monitoring: The Butte County Department of Development Services shall ensure the condition is met at the time of construction activities. 4. Mitigation Measure CUL-1 Place a note on a separate document which is to be recorded concurrently with the map or on an additional map sheet that states: “If grading activities reveal the presence of prehistoric or historic cultural resources (i.e., artifact concentrations, including arrowheads and other stone tools or chipping debris, cans glass, etc.; structural remains; human skeletal remains) work within 50 feet of the find shall immediately cease until a qualified professional archaeologist can be consulted to evaluate the find and implement appropriate mitigation procedures. If human skeletal remains are encountered, State law requires immediate notification of the County Coroner (530.538.7404). If the County Coroner determines that the remains are in an archaeological context, the Native American Heritage Commission in Sacramento shall be notified immediately, pursuant to State Law, to arrange for Native American participation in determining the disposition of such remains.” The provisions of this mitigation shall be followed during construction of all subdivision improvements, including land clearing, road construction, utility installation, and building site development. Plan Requirements: This note shall be placed on a separate document which is to be recorded concurrently with the final map or on an additional map sheet and shall be shown on all site development and building plans.  Butte County Department of Development Services   Conditions of Approval – CG Development, Inc.
