E. Environmental Setting
The project site is located at 7300 Chevron Way which intersects with Midway Road in unincorporated Solano County; east of the boundaries of the City of Vacaville and approximately .33 of a mile from the Interstate 80 and Midway Road interchange. The Assessor’s Parcel Number is 0109-230-170 and the entire parcel is 17.6 acres in size. The parcel is bisected by a 60’ public road known as Chevron Way. The approximately 9-acre portion on the west side of Chevron Way is vacant of structures and is covered in grasses. The developed portion of the parcel is on the eastern side of Chevron Way and is approximately 7.5 acres in size. The 7.5 portion of the parcel is currently used by D/K Dixon for the operation of a hazardous waste storage and transfer facility to collect, store, and transfer used oil, oily wastewater, and waste antifreeze from off-site generators located within a 100-mile radius.
Current development on the project site includes:
One (1) 50’ x 50’ modular office building (2500 sq. ft.)
One (1) 50 x 100’ warehouse building (5000 sq. ft.)
One (1) 24’ x 60’ modular office trailer used as a training room and locker room
One (1) remediation compound - 1785 sq. ft.
One (1) elevated concrete loading dock
One (1) office trailer used for the Transfer Facility Office (445 sq. ft.)
One (1) wood building used as the Transfer Facility Laboratory Office (128 sq. ft.)

One (1) concrete and cinder block - secondary containment for above-ground diesel fuel tank (diesel tank not in use)
Six (6) above ground storage tanks totaling 50,000- gallon capacity
The 7.5-acre portion of the parcel is bordered by a chain link fence with two entry gates - one near the office building and one near the loading dock area and one near the existing loading dock area. Both of these gates are accessed from Chevron Way.
There is a row of mature trees (oaks and pines) along with several bushes, located along the frontage of the property bordering Midway Road. The entire compound has been graded and majority of the site is covered in weathered asphalt in parking and traffic areas and with concrete pads in the storage tank areas. The remaining portion of the compound is covered in gravel with some native soil along the eastern most boundary. The property is flat with 0-6% slopes and drainage flows east to west.
The land use on the surrounding properties includes California Pipe business to the south, an RV storage business to the southwest, vacant highway commercial property directly north and a Sheldon Gas storage tank facility to the east. Prior to the Sheldon Gas parcel there is a flood control easement for the Sweeney Channel, which is part of the Ulatis Flood Control Project managed by the Solano County Water Agency. Other manmade drainage channels sit along the north, west and south side of the parcel. The nearest residential dwelling is approximately .10 of a mile northwest on an agricultural property located east of the vacant highway commercial property. The Sacramento Veterans Cemetery entrance is approximately .75 of a mile to the east.
Potable water is provided by Solano Irrigation District. A septic system and all other utilities are also located onsite. There is outdoor security lighting around the tanks and buildings. There is a 4’ x 8’ business identification sign located on the chain link fence facing the northwest (main) entrance to the facility.
Site History:
A wholesale distribution operation for petroleum products and related petroleum equipment facilities (BC Stocking) was approved to operate on the site in 1978 by the Solano County Planning Commission. A new use permit was approved in 1991 for the same petroleum product business. There were subsequent revisions to the use permit (Minor Revision No. 2) which added the hazardous waste storage and transfer facility to collect, store, and transfer used oil, oily wastewater and waste antifreeze from off-site generators. This use permit was extended by the Solano County Planning Commission in 2002 through 2012. The current property owner (Advanced Environmental) purchased the property in 2004 and applied for a 4th revision to the use permit in 2012 to add a modular office trailer. This 4th minor revision application was subsequently revised and resubmitted in 2017 which is the project identified as Amendment 1 to Use Permit U-91-17 and is defined in the project description below.
F. Project Description
In addition to the continuation of the hazardous waste storage and transfer facility that collects, stores and transfers used oil, oily wastewater, and waste antifreeze from off-site generators, D/K Dixon is proposing to add an additional waste transfer tank farm to receive and manage the same types of wastes as they do today (used oil, oily wastewater and waste antifreeze). D/K Dixon is also proposing to install a new product antifreeze blending and storage unit, as well as a new pit-type truck scale.
A summary of proposed changes is described below:
1. Construct a 4,000 sq. ft. Waste Transfer Tank Farm to include:
a. Install seven (7), 33,000-gallon horizontal, UL-142, AST tanks - five (5) tanks to contain used oil, one (1) tank to contain used glycol (spent antifreeze); and one (1) tank to contain storm water. Six of the seven tanks will have split compartments, 16,500-gallon capacity each. (Note: these volumes are approximate as designed prior to construction);
b. Install one (1) 1,200-gallon vertical tank to contain carbon which will be used to filter storm water so that storm water will meet discharge requirements prior to discharging;
c. Install a drum storage area to contain one hundred twenty (120), 55-gallon drums to store Non-RCRA liquid and solid waste;
d. Construct Secondary Containment system for the new Tank Farm.
2. Construct one (1) 2,400 sq. ft. truck loading and unloading area for the new Tank Farm.

There are no proposed changes to the operating hours or in the number of employees with this project.
No new lighting other than security lighting around the new tank farms is proposed. There is a 4’ x 8’ business identification sign located on the chain link fence facing the northwest (main) entrance to the facility. No new signage is proposed.
Discussion and Analysis
G. General Plan and Zoning Consistency
General Plan
The General Plan designation for the D/K Dixon property is Urban Commercial/Municipal Service Areas. Urban Commercial allows for commercial and non-commercial uses. The property is located within a Municipal Service Area (MSA) outside the city limits of Vacaville. Because of the MSA designation, permanent commercial uses cannot occur until the property is annexed into the city of Vacaville. The applicant is not proposing a new land use; the property has been used as a transfer station for petroleum products since 1978 and will continue to operate as a transfer station for new, used, and recycled oil, oily wastewater and antifreeze. As described in the above project description, the project is in compliance with the 2008 Solano County General Plan.
Zoning
The property is zoned Exclusive Agricultural(A-40). Per Table 28.21A of the Solano County Zoning Regulations, refuse, disposal, incineration, recycling or composting is allowed with an approved conditional use permit. Per Table 28.21A, transitional industrial uses are allowed in the A-40 zones after obtaining a minor use permit. The property has been used as a storage and transfer business for almost 40 years when a conditional use permit was approved by the Solano County Planning Commission in 1978.
As mentioned above, the property falls within an MSA; land uses located within the boundaries of an MSA are considered a Transitional Commercial Use in Section 28.76 of the Zoning Regulations which limits urban commercial uses to a fixed term of ten years. Transitional Commercial uses also requires any new construction to be temporary in nature so that they can be removed upon annexation. Properties within MSA’s outside of Vacaville requires new buildings, structures, and landscaping to meet the City of Vacaville’s design guidelines. The proposed project is not a new use. All proposed construction, installation of storage tanks and truck scale, are temporary construction and are proposed within the existing disturbed footprint of the existing facility. The use permit will be limited to ten years in the conditions of approval. After ten years, the applicant may approach the Solano County Department of Resource Management and the City of Vacaville for renewal options at that time.
H. Environmental Analysis
An Initial Study and Negative Declaration have been prepared for the project and circulated for public review. The public comment period expired February 26, 2018. Four comment letters were received and are included as Attachment D.
Letter #1 - State Clearinghouse and Planning Unit
The State Clearinghouse and Planning Unit act as the clearinghouse for environmental documents being processed throughout the state of California. The Clearinghouse sends environmental documents to other state agencies and collects their responses to send to the lead agency responsible for preparing the final environmental document. A list of the agencies routed the D/K Dixon Draft Initial Study and Negative Declaration are shown on the Document Details Report page included in the letter from the Clearinghouse. The Central Valley Regional Quality Control Board sent comments to the Clearinghouse; as well as to Solano County (see Letter #2).
Letter #2 - Central Valley Regional Water Quality Control Board
A comment letter was received from the Central Valley Regional Water Quality Control Board listing potential permits that D/K Dixon may need to obtain for their proposed expansion project. The operator and the Solano County Environmental Health Division are aware that existing permits will need to be updated and condition of approval No. 17 listed below, requires D/K Dixon to obtain all necessary and required permits from the Central Valley Regional Quality Control Board.
Letter #3 - Caltrans
A comment letter was received from Caltrans regarding D/K Dixon’s Construction General Permit and Storm Water Pollution Prevention Plan (SWPPP). D/K Dixon has a SWPPP on file with the Central Valley Regional Water Quality Control Board and will be updating their Construction Permit and SWPPP as part of the permitting process; this would come after the review and approval of the land use permit by the Solano County Planning Commission. Condition of approval No. 22 requiring these permits to be updated is included below.
Letter #4 - Department of Toxic Substances
A comment letter was received from the Department of Toxic Substances (DTSC). The DTSC letter stated that it is their belief that the environmental baseline for the proposed project’s environmental review is the year 2008; this is the year that DTSC processed an Initial Study/Negative Declaration for D/K Dixon for a renewal of their DTSC Class C Standardized Permit. However, per CEQA, the baseline established for environmental review of a project is based upon the existing conditions at the site at the time environmental review begins. Therefore, the current existing use of the D/K Dixon facility was used as the environmental baseline for County staff when evaluating the proposed expansion project. The applicant is proposing no changes to the existing hours of operation, no changes in the amount of trucks entering/existing the site (approximately 25 per day), no changes in the number of employees, thus there would be no significant impacts to air quality, traffic, noise, and greenhouse gas emissions with the addition of this project.
During the initial review of the project, the applicant supplied Solano County Public Works Engineering with the details of truck trips to and from the property on an average day for the facility. The information was reviewed by Public Works Engineering staff who determined that this amount of truck traffic would not have a significant impact to Midway Road or to Chevron Way. No road improvements are required nor is a road impact fee imposed by the Public Works Engineering Division.
Trucks Arriving:
9 - 3 axles truck - 10 tons
3 - 2 axle trucks - 7 tons
4 - 2 axle tankers - 9 tons
Trucks Departing:
6 - 3 axle trucks - 24 tons
The project was also reviewed by the Yolo-Solano Air Quality Control District which stated that no permits were needed from the District unless demolition of any of the manufactured units were to take place due to potential asbestos in those units. As noted in the project description, the demolition of the manufactured units is not part of this proposed project.
Staff has reviewed the Tribal Cultural Resources inclusion on the Initial Study Checklist. This included reviewing the requirements under Section 21080.3.1 of CEQA which requires consultation with a tribe prior to the release of a Negative Declaration, Mitigated Negative Declaration or Environmental Review if the tribe has made a written request to be notified of proposed projects within its geographic area of affiliation, and upon notification by the lead agency, the tribe responds in writing within 30 days of receiving such notice. At this time, no tribe has made a request for such a notice of projects in the D/K Dixon area. As stated in the project description, this site has been historically disturbed for a number of years and it is unlikely that any tribal cultural resource would be significantly impacted by the proposed project. However, condition of approval No. 5 is included which states that if any cultural or tribal resource is discovered during construction activities, the applicant shall cease construction and notify the Solano County Coroner if human remains are found or notify the State Native American Heritage Commission if tribal resources are discovered.
In summary, the Negative Declaration found that the project could not have a significant effect on the environment. Details regarding each of the California Environmental Quality Act (CEQA) checklist items considered for this project are discussed in Attachment C.
I. Project Review and Analysis
As noted above, this project site has been in operation since the late 1970’s beginning as a wholesale petroleum distribution business then converting to a hazardous waste collection, storage, and transfer facility in 1991 with a new use permit. The applicant is requesting the continuation of this operation and the addition of waste transfer tank farm, the addition of a new anti-freeze blending facility and a new pit-type truck scale. Per Table 28.21A of the Solano County Zoning Regulations, refuse, disposal, incineration, recycling or composting is allowed in the A-40 zoning district with the approval of a use permit. D/K Dixon assumed the operations in 2004 and has been diligent in keeping the operation in compliance with the existing use permit.
As part of the Department of Resource Management project review process, the application Initial Study, and Negative Declaration have been reviewed by various County Departments, as well as other local agencies. Any recommended conditions of approval have been incorporated into the use permit resolution.
Solano County Building Division
The Building Division reviewed the application and commented that the construction of the new tank farms, truck scale and parking lot striping will require approval of a building permit. Conditions of approval requiring necessary building permits is included below.
Solano County Public Works Engineering Division
Chevron Way is a County of Solano maintained road. Any on-site grading and driveway improvements will require a grading permit and encroachment permit as noted in the conditions of approval below. As part of the grading permit review, the applicant will be required to submit a drainage plan showing all off-site and on-site improvements necessary to manage storm water issues related to the development.
Solano County Environmental Health Division
The project was reviewed by the Environmental Health Division Technical Section and Hazardous Materials Section. The conditions of approval require the permittee to contact the Central Valley California Regional Water Quality Control and the Department of Toxic Substances to obtain any and all required permits based upon this expansion.
Solano Irrigation District
The project was reviewed by the Solano Irrigation District which provides potable water to the facility. A complete list of their requirements is included below.
Yolo-Solano Air Quality Management District
The project was reviewed by the Yolo-Solano Air Quality Control District (YSAQMD) and responded that the toxicity of the products handled by D/K Dixon does not warrant a permit through their jurisdiction. YSAQMD did note that the if demolition of the manufactured offices was to take place, permits would be required from them as asbestos may be exposed during the demolition. No demolition of the offices is planned with the proposed project.
Dixon Fire Department
The project was reviewed by the Dixon Fire Department which provides fire protection to the facility. A complete list of their requirements is included in the conditions of approval below.
City of Vacaville
No comments were received from the City of Vacaville.
FINDINGS:
1. The establishment, maintenance, or operation of the proposed use is in conformity with the County General Plan with regard to traffic circulations, population densities and distribution, and other aspects of the General Plan.
The General Plan designation for the D/K Dixon property is Urban Commercial/Municipal Service Areas. Urban Commercial allows for commercial and non-commercial uses. The property is located within a Municipal Service Area (MSA) outside the city limits of Vacaville. Because of the MSA designation, permanent commercial uses cannot occur until the property is annexed into the city of Vacaville. The applicant is not proposing a new land use; the property has been used as a transfer station for petroleum products since 1978 and will continue to operate as a transfer station for new, used, and recycled oil, oily wastewater and antifreeze. As described in the above project description, the project is in compliance with the 2008 Solano County General Plan.
2. Adequate utilities, access roads, drainage and other necessary facilities have been or are being provided.
Vehicular access to the site will continue to be from Chevron Way, a public road located off Midway Road. The site has existing electrical power and the building plans will be reviewed and approved by the Solano County Building and Safety Division before a permit is issued. Grading and drainage plans will be reviewed and approved by the Public Works Engineering Division. The Solano Irrigation District supplies potable water to the site and the site maintains an on-site septic system.
3. The subject use will not, under the circumstances of the particular case, constitute a nuisance or be detrimental to the health, safety, peace, morals, comfort or general welfare of persons residing or working in or passing through the neighborhood of such proposed use, or be detrimental or injurious to property and improvements in the neighborhood or to the general welfare of the County.
A Draft Initial Study and Negative Declaration was prepared and circulated by the Department of Resource Management. No potentially significant adverse environmental impacts are likely to occur with this project. Implementation of conditions of approval would prevent the project from creating significant effects to the persons residing or working in, or passing through the neighborhood; nor would the conditioned project be detrimental or injurious to property and improvements in the neighborhood or to the general welfare of the County.
