In the event Contractor fails to obtain such indemnity obligations from others as required herein, Contractor agrees to be fully responsible according to the terms of this section. Failure of City to monitor compliance with these requirements imposes no additional obligations on City and will in no way act as a waiver of any rights hereunder. This obligation to indemnify and defend City as set forth herein is binding on the successors, assigns or heirs of Contractor and shall survive the termination of this Agreement or this section.
(d) City’s Negligence . The provisions of this section do not apply to claims occurring as a result of City’s sole negligence.

SECTION 18. ASSIGNMENT.

The expertise and experience of Contractor are material considerations for this Agreement.

In recognition of that interest, Contractor shall not assign or transfer this Agreement or any portion of this Agreement or the performance of any of Contractor ’s duties or obligations under this Agreement without the prior written consent of the City.

Any attempted assignment shall be ineffective, null and void, and shall constitute a material breach of this Agreement entitling City to any and all remedies at law or in equity, including termination of this Agreement pursuant to Section 20 “Termination of Agreement.” City acknowledges, however, that Contractor, in the performance of its duties pursuant to this Agreement, may utilize subcontractors.

SECTION 21. DEFAULT.

This timeframe is presumptively thirty (30) days, but may be extended, though not reduced, if circumstances warrant. Dur ing the period of time that Contractor is in default, the City shall hold all invoices and shall, when the default is cured, proceed with payment on the invoices. In the alternative, the City may, in its sole discretion, elect to pay some or all of the outstanding invoices during the period of default. If Contractor does not cure the default, the City may take necessary steps to terminate this Agreement under Section 20 “Termination of Agreement.” Any failure on the part of the City to give notice of the Contractor’s default shall not be deemed to result in a waiver of the City’s legal rights or any rights arising out of any provision of this Agreement.

SUMMARY
SCS Engineers (SCS) is pleased to present this proposal to the City of Cathedral City (City) for consulting services related to the development and implementation of effective cannabis odor control strategies. This proposal has been prepared in response to the Scope of Work (SOW) provided to SCS on April 15th, 2025. Our proposal provides references and project descriptions that illustrate our expertise in this area. Additional sections detail the scope of work to be performed by task as well as associated budgets.

With the majority of United States and the District of Columbia having legalized recreational and/or medicinal cannabis, a significant problem has emerged in several regions related to the mitigation, regulation, and assessment of the odor generated by cannabis cultivation and processing activities.

This issue is complicated as odors are subjective and the nature and composition of cannabis odor are highly variable. In addition, different societies have inherently different levels of acceptance for odors in their communities. Regulators at the state, regional, and local levels are attempting to deal with these complex issues through a combination of permitting, land use, and nuisance rules. The cannabis odor situation in Cathedral City is no different, and currently, the municipality is working to find a balance between responsible cannabis cultivation and impacted citizens.

We feel strongly that SCS is an ideal candidate to successfully meet the City’s goals for several reasons, including the following:

Broad experience with development of effective odor control planning and abatement strategies for various applications and facility types. SCS has been a leading expert in odor control planning, air quality regulatory navigation and support, and empirically assessing odor using a brand-agnostic approach to solving odor issues with a focus on system efficacy. SCS has operated air monitoring stations, worked with various facility types, and supported various odor generating industries to resolve air quality and odor issues, reporting data to CA state and local agencies for over 30 years.

Strong familiarity with the challenges that arise in developing effective and tactful cannabis odor regulation. The nature of cannabis odor emissions is complex and influenced by a significant number of variables. SCS has assessed cannabis emissions with adequate spatial and temporal density to understand how variables such as light, type of process, cannabis strain, and stage of maturity affect how odor emissions occur. We understand project goals, and the proposed approach will reflect this.

We will work to develop and implement effective cannabis odor control strategies through regulatory review and best practice assessments. SCS’s experience with odor control technology evaluation, odor control permitting, inspection and verification will be a direct benefit to the City.

A strong project team with extensive experience working together, committed to supporting the project for its entire duration. We are a collaborative and responsive team, committed to dedicating the necessary resources to meet the project schedule while drawing on our proven history to deliver outstanding insight, quality, and service.

Local personnel. We have experienced, bilingual personnel based in the Imperial Valley who are also community members and stakeholders. Our personnel are employees, not subcontractors.

References and Past Project Profiles are provided as Appendix C. The following sections provide more detail as requested in the RFP.

TECHNICAL WORK PLAN AND RESPONSE TO STATEMENT OF

WORK (SOW)
The City currently has 47 operating cannabis businesses with 67 licenses and another 17 non- operating businesses that hold 38 licenses. Currently the City has Municipal Code (9.108.080.A) that requires odor control. However, the City does not have a process for the periodic review and verification of system performance. The City does, however, have a public nuisance regulation under Section 13.80.240 that requires cannabis odors to not cross property lines or be detectable in an adjacent or nearby unit. Currently the City has a moratorium on new cannabis conditional use permits as of February 26th, 2025. This moratorium was put in place in response to a large influx of odor complaints in 2024 and continuing into 2025.

With a strong track record in environmental compliance and third-party verification, our team operates within some of the most stringently regulated sectors, including projects subject to U.S. EPA standards. This experience has reinforced our commitment to rigorous data integrity, thorough documentation practices, and defensible field methodologies, which directly inform our approach to regulatory compliance in the cannabis sector. We understand the importance of consistent, enforceable inspection protocols that support responsible operation within the community, while remaining practical for facility operators.

In addition, we can offer optional third-party audit services to The City on an as-needed basis, supporting enforcement efforts with field-tested, best practices.

Task 1: Regulatory Review and Best Practices Assessment The City has requested the following:
 Provide specific recommendations for minimum, enforceable odor control requirements that establish clear, measurable, and attainable standards for cannabis odor mitigation as a condition of approval for a cannabis conditional use permit.

SCS recognizes the regulatory challenges of providing guidance to a relatively new and growing industry, particularly one fraught with legal complications, nuisance complaints, and public regulatory expectations related to managing nuisance odor. SCS is well-versed in odor science and has conducted scientific studies assessing the nature of cannabis odor, presented on odor science and regulatory guidance at national cannabis industry events, and conducts in-house olfactometry and odor abatement planning.

We will evaluate best practices in the cannabis industry to guide the development of the City’s odor mitigation and assessment standards, which will be required for cannabis conditional use permit approvals. SCS will make regulatory recommendations based on facility type, zoning, and provisional review of the operator’s odor control planning documentation.

Deliverable: Report section detailing our assessment of the City’s existing odor control and enforcement regulations related to cannabis activities, along with specific, enforceable recommendations for minimum odor mitigation standards required for conditional use permit approval.

Task 2: Odor Control Technology Evaluation
For this Task, the City has requested the following:
 Evaluate and distinguish between odor control requirements for:

Attachment 1 to Exhibit "A"

Cathedral City | Proposal for Consulting Services Related to Cannabis Odor Control

o Cannabis cultivation and manufacturing operations, which typically have higher odor emissions.
o Retail dispensaries, which may require different, less intensive controls.  Offer recommendations on generally available, proven technologies (avoiding proprietary systems) and outline their effectiveness, costs, and maintenance needs.  Identify the suitability of specific technologies by business type (cultivation, manufacturing, retail) and facility size.

SCS is well versed in odor investigations related to landfills, recycling centers, compost facilities, and water treatment plants. In the cannabis industry, we have extensive experience in vetting odor mitigation technologies as an independent third-party. We have been contracted by cannabis cultivators and odor control technology manufacturers alike to assess a range of solutions for their effectiveness in odor mitigation in-field. These technologies have included vapor phase odor neutralizers, carbon adsorption systems with various pretreatment options, photo-catalytic oxidation, as well as different chemical scrubbing technologies.

Previous project scopes have included:
 Measuring single pass-through efficiencies of scrubber technologies;  Assessing the odor reduction in a given space when an array of scrubbers are turned on compared to when they are off; and
 Comparing up- and down-wind differentials in odor concentration to measure a facility’s impact at the fence-line or at down-wind communities.

All field investigations were conducted using established sampling methods and analyzed via olfactometry. In addition, specific chemical analysis was also performed.

While project details are subject to confidentiality agreements, this background gives us a unique vantage point on what technologies are most effective and practical for different types of cannabis operations.

For Task 2, we will:
 Conduct a market-level review of available, non-proprietary odor control technologies;  Differentiate technology suitability across business types, such as cultivation, manufacturing, and retail, with consideration for facility size and typical emission profiles;  Provide comparative summaries based on each technology’s effectiveness in different situations, capital and operational costs, as well as maintenance needs and expected lifespans;
 Develop basic standard operation procedures (SOPs) for routine maintenance and performance checks tailored to each technology type; and  Provide third-party testing, if requested, using established field methodologies to assess odor control effectiveness.

Deliverable: Report section detailing an analysis of odor control technologies and assessment of their effectiveness while providing insight on operational parameters.

Task 3: Odor Control Permitting Process
For this Task, the City has requested the following:

Attachment 1 to Exhibit "A"

Cathedral City | Proposal for Consulting Services Related to Cannabis Odor Control

 Assess odor control permit processes from other jurisdictions (staff will provide a list of researched cities) to identify best practices.
 Prepare specific recommendations for creating an odor control permit process, placing responsibility on cannabis businesses to design and propose site-specific odor control solutions.
 Outline the review and verification process, including:
o Submittal checklists with detailed equipment specifications, maintenance schedules, and media replacement requirements.
o Minimum qualifications for third-party odor control plan preparers.  Recommend a process for initial and renewal reviews of odor control permits.

SCS has extensive experience in developing effective odor control systems and odor abatement plans using regulatory frameworks influenced by those in states like Washington and Colorado, where cannabis odors are addressed under general air quality regulations rather than cannabis- specific rules. We understand how to balance the need for strong, enforceable regulations with the practical challenges cannabis operators face in implementing and maintaining effective odor control strategies. SCS shall:
 Assessment of Comparable Jurisdictions’ Odor Control Permitting Process Review odor control permit processes from the City-provided list of jurisdictions, identify best practices, regulatory frameworks, enforcement mechanisms, and common challenges, and summarize findings in a comparative matrix highlighting key similarities, differences, and innovative approaches.
 Thorough Documentation for Best Practices for Odor Control Planning & Regulatory Review SCS will make specific recommendations for creating an odor control permit process with focus on balancing industry and regulatory needs within a robust and defensible odor control planning system, focusing on what presently works, is practical, and tested solutions from the odor control industry, with recommendations specific to the City’s review of odor control plans.
o With extensive background knowledge on existing odor mitigation technologies, we are able to provide quantifiable evidence related to effectiveness and recommended schedules for maintenance and consumables replacement.
o We will design a clear, step-by-step review and verification process for approving operator-chosen site-specific odor control solutions based on our experience in testing and assessing odor mitigation technologies.

Deliverable: Report section detailing recommendations for the odor control permitting process and renewal, with a focus on odor control solution specifications and qualifications for third-party authors of odor abatement plans.

Task 4: Inspection and Verification Protocols
For this Task, The City has requested the following:
 Prepare recommendations for inspection checklists and required documentation for both scheduled and ad hoc inspections.
 Specify how cannabis businesses should demonstrate ongoing compliance, including requirements for performance testing or third-party verification.

Attachment 1 to Exhibit "A"

Cathedral City | Proposal for Consulting Services Related to Cannabis Odor Control

 Identify enforcement triggers, such as data thresholds or complaint patterns that warrant inspections or corrective action.

SCS shall:
 Develop Standardized Inspection Checklists and Required Documentation We will prepare comprehensive inspection templates for both scheduled and ad hoc site visits, tailored to the specific activities of cultivation, manufacturing, processing, and retail facilities. These checklists will include:
o Verification of odor control systems’ operational status and maintenance history o Documentation of employee training on odor mitigation protocols o Logs for odor complaints, community outreach, and response actions o Inspection of facility design features that influence odor containment (e.g., negative pressure zones, filtration systems)
o Air quality testing records, when applicable
 Define Measures for Demonstrating Ongoing Compliance
To verify that facilities maintain continuous compliance, we will outline clear expectations, including:
o Minimum testing frequencies for odor control system performance (e.g., quarterly internal checks, annual third-party evaluations) using independent verification (e.g., olfactometry data, chemical analysis) to validate odor containment o Required documentation for equipment servicing and filter replacements  Establish Enforcement Triggers Based on Objective Criteria We will identify actionable thresholds that justify City mediation, including:
o Complaint-based triggers
o Performance-based triggers (e.g., evidence of malfunctioning odor control systems or failure to meet testing benchmarks)
o Documentation lapses or repeat violations
o Exceedance of predefined odor detection levels
This approach can verify that cannabis businesses are held to consistent, transparent standards that protect community well-being while recognizing the operational realities of each license type. SCS already has several routine operations and maintenance checklists previously developed which are a great starting place for developing City specific documentation.

Deliverable: Report section detailing inspection and verification protocols, including inspection templates and checklists, descriptions for on-going compliance, and performance testing.

Task 5: Stakeholder Engagement and Presentations
For this Task, The City has requested the following:
 Review and comment on draft ordinance prepared by City staff.  Present to the City’s Cannabis Task Force, Planning Commission, and City Council on cannabis odor control strategies.

Attachment 1 to Exhibit "A"

Cathedral City | Proposal for Consulting Services Related to Cannabis Odor Control

 Specify that the consultant will serve as a resource and subject matter expert during public meetings.

SCS personnel will be made available for presentations to City staff, the City’s Cannabis Task Force, Planning Commission, and City Council on cannabis odor control strategies. Our team has provided expert witness testimony and odor management expertise support for several Board of Supervisor hearings on the topic of cannabis odor management. SCS Engineers’ Vice President and Project Director, Paul Schafer, is a designated SCS leading expert on Air Quality & Odor Management and he and his team are regularly brought into projects across the US to advise on air quality and odor issues. Mr. Schafer’s team has provided support on a multitude of odor management projects and has presented findings to both governmental and industry stakeholders nationally. Our team features bilingual capability and local expertise familiar with the Cathedral City region and can provide in-person and online advisement for a range of stakeholder engagements.

Deliverable: SCS Team on-call and in-person support, as requested by City personnel.

Task 6: Training
For this Task, the City has requested the following:
 Provide training to planning and code enforcement staff on cannabis odor control, including any newly established odor control permitting process and post-construction inspections.

SCS will provide training to the City’s planning and code enforcement staff on cannabis odor control, covering topics such as methods for conducting both planned and ad hoc on-site inspections of cannabis odor-generating facilities, and the use of guided checklists for odor abatement plan reviews and site inspections. Drawing on our experience conducting odor audits within the cannabis industry, SCS is familiar with common nuisance odor issues, industry best practices, and methods for evaluating odors both on-site and through certified odor laboratories. We will advise the City on the appropriate use, benefits, and limitations of each evaluation approach.

Deliverable: Provide on-site inspection training to City staff, including supporting checklists and detailed instructions for reviewing odor control systems across different types of cannabis facilities.

Training will cover how to assess odor control technologies, evaluate operation and maintenance records, and review odor control plans, enabling inspectors and City personnel to conduct informed site visits and check compliance at cultivation, manufacturing, and retail locations.

Optional Task 7: Third Party Reviews of Odor Control Permits For this Task, The City has requested the following:
 Perform third-party reviews of odor control permits, should an odor control permitting process be established by the City.

SCS has generated dozens of odor control and abatement plans for the cannabis industry across the nation and is widely considered a leading authority on Air Quality and Odor Science. SCS proposes on-going City odor control plan review to assess regulatory compliance with emphasis on measurable data and industry proven solutions, with focus on accountability and widespread industry-adoptability of technical odor control site recommendations. Some facets of regulatory review of odor control plans include:
 Proactive mitigation strategies focused on:
o Facility siting and zoning compliance

The City of Marina commissioned SCS Engineers, with support from ReGen Monterey and Monterey One Water, to conduct an Odor Attribution Study aimed at identifying and ranking potential sources of intermittent odor complaints. The study focused on assessing the relative contributions of a regional landfill, wastewater treatment plant, composting facility, and adjacent agricultural operations.

Using industry-standard methods and trained personnel, SCS developed and executed a detailed odor investigation plan, integrating odor complaint data, meteorological conditions, and direct source measurements. The study’s findings inform targeted mitigation strategies, ensuring resources are directed to the sources most responsible for odor impacts. The report also outlines recommended best practices, quality assurance protocols, and the next steps, and was reviewed with stakeholders during a public outreach meeting.

PROJECT PROFILES
The project profiles that follow have been selected as a representative sampling of work we have completed that is relevant to the scope requested by this RFP. We believe these project narratives demonstrate our ability to meet all City’s service needs and address the comprehensive scope, work plan and Statement of Work (SOW) tasks.

Pacific Stone Roadside Odor Study 2022-2023
Carpinteria, CA
Background
The purpose of this sampling campaign was to measure
and determine the efficiency of Envinity Group scrubbers inside a greenhouse relative to reducing odors and odor- responsible molecules. A secondary goal was to assess
the potential of trace level Total Reduced Sulfur (TRS) measurements to be used as a surrogate for odor
emission potential from a cannabis greenhouse.

Ultimately, the goal is to significantly reduce nuisance odors escaping greenhouse facilities. Two greenhouses of similar size, climate control methodologies, location—and thus, environmental factors—and plant composition were
used in this study: one equipped with fifteen (15)
operating scrubber units, and one with no scrubber units in operation.

A total of 240 air samples were collected from multiple predetermined indoor and outdoor locations over two-hour and four-hour intervals to assess odor emissions from two cannabis greenhouses. Uniform sampling tubing, pre-
labeled sample bags, and protective measures ensured
consistency and minimized contamination. Trained
personnel used a custom app to track samples and ensure analysis within a 36-hour holding time. Samples were
transported to a laboratory for sequential odor panel
evaluation using an olfactometer, followed by TRS concentration analysis via a proprietary monitoring system. Initial manual TRS readings were later automated with a multiplexer system.

Additional influent and effluent samples from selected scrubbers were collected to evaluate single- pass odor removal efficiency. The study showed that given adequate spatial density of scubbers, as demonstrated by this study, the scrubbers are capable of reducing odor emissions to a level that would result in no perceivable cannabis odors downwind from the subject facility. Results were provided to the client team in a comprehensive report.

The project cost was approximately $150,000 total over multiple studies.

Challenges
Several key challenges
were encountered during
the study. First,
simultaneous harvests at
both greenhouses
required significant
coordination, deviating
from typical staggered
harvest practices.

Second, to analyze a
larger number of samples
within the 36-hour
holding window, the
project team established an in-house odor panel using a newly acquired olfactometer and screened nearly 90
individuals to identify 29 qualified panelists, enabling around-the-clock analysis. This eliminated reliance on a remote lab and avoided courier delays. Lastly, sourcing 60L PTFE sample bags from Scentroid presented logistical hurdles due to custom manufacturing, international shipping, and customs issues, though these bags offered superior odor compound retention and sample integrity compared to previously used materials. Considering these logistical challenges, SCS successfully accomplished the data collection and analytical efforts, and the project yielded a robust third-party report that detailed the efficacy of the novel greenhouse scrubber odor control technology.

Santa Barbara County – Odor Abatement Plans 2018-Present Multiple Clients, C A
Background
SCS Engineers has extensive experience in the development of Odor Abatement Plans (OAPs) to support cannabis cultivators, merchants, processors, and distributors in achieving compliance with Santa Barbara County cannabis regulations. As part of the permitting process for a range of facility types—including indoor, outdoor, and greenhouse operations—SCS has collaborated with both regulatory agencies and industry operators to produce comprehensive, site-specific OAPs.

Each OAP prepared by SCS addresses the full suite of regulatory requirements, including:
 Site-specific information regarding facility layout, zoning compliance, and proximity to sensitive receptors
 Identification and characterization of odor-emitting activities and operational phases  Detailed descriptions of odor control technologies and mitigation methods  Certification of the odor control system by a Certified Industrial Hygienist (CIH) and a Professional Engineer (PE)
 Designation of a local primary contact for odor complaint response Olfactometry panelists analyzing samples

 Provision for regulatory access to facilities
 Corrective action procedures in response to verified odor complaints The OAPs also outline requirements for odor sampling and testing, air exchange rates, system operation and maintenance protocols, and performance testing procedures to verify the efficacy of odor control measures.

Project cost per OAP typically ranges between $10,000 to $20,000, depending on the facility type and odor abatement strategy required to address the odor impacts on adjacent sensitive receptors.

Challenges
Given the dynamic regulatory landscape surrounding cannabis operations in Santa Barbara County, SCS routinely updates OAPs to reflect substantive changes to the County’s odor control ordinances.

To date, SCS has prepared dozens of OAPs for cannabis operators including Headwaters, Pacific Dutch Group, Everbloom, and others, and can provide sample OAPs upon request.
