Service Delivery Models

The cost structure of a solid waste system depends fundamentally on how the service is delivered. Three dominant models shape the financial framework: municipal (city-operated), franchise (exclusive agreement with a private hauler), and contract (competitive bid from private providers). Understanding how each model affects cost allocation and revenue requirement is critical for accurate rate-setting.

Learning Objectives

  • Distinguish between municipal, franchise, and contract service delivery models
  • Explain how COS methodology and cost allocation differ under each model
  • Identify which model applies to a given situation and the implications for rate design
  • Recognize hybrid models where cities operate some services while contracting others

The Three Primary Models

Municipal (Government-Operated)

Who operates: City or county government owns trucks, employs drivers, manages routes directly.

Revenue model: Full cost recovery through solid waste rates.

Key costs: Labor (drivers, mechanics, supervisors), fuel, equipment depreciation, maintenance, tipping fees, administration.

COS consideration: The utility funds all operational costs directly. No private profit margin. Test year reflects actual municipal budget.

Franchise Model

Who operates: Private company holds exclusive agreement to provide service. City grants franchise rights for defined territory.

Revenue model: Ratepayers pay a franchise fee (rate) to the operator. Operator recovers allowable costs plus negotiated profit margin (typically 7–15%).

Key costs: Operator’s documented collection, disposal, and administrative costs, plus profit.

COS consideration: Study focuses on what costs are "allowable" under franchise agreement and what profit margin is reasonable. Less flexibility in cost recovery.

Contract Model

Who operates: City competitively bids collection and/or disposal services. Multiple providers can compete.

Revenue model: City negotiates lump-sum or unit-price contracts. Costs are fixed by contract terms, not by the operator’s actual expenses.

Key costs: Whatever the winning bid specifies — often more competitive than cost-plus approaches.

COS consideration: COS study reflects the competitive contract rate, not the operator’s internal costs. Rates are market-based, not cost-justified.

How Revenue Requirements Differ by Model

The foundation for rates differs significantly depending on service delivery model:

Municipal

Revenue Requirement = Full Cost Recovery

Municipal utilities must recover 100% of operating costs through rates. Budget + adjustments = test year = revenue requirement.

Example: Revenue requirement = sum of collection, disposal, and administrative costs, all documented from the municipal budget.

Franchise

Revenue Requirement = Allowable Costs + Profit Margin

Franchise operator recovers documented allowable costs plus negotiated profit. City scrutinizes costs but operator earns return.

Example: Allowable costs plus negotiated profit margin (typically 7–15%) = total revenue requirement.

Contract (Competitive)

Revenue Requirement = Winning Bid Price

Market competition determines price. May be lower than cost-of-service if competition is robust; may include vendor profit, risk contingency.

Example: Competitive bid yields a contract rate the city pays regardless of what municipal operation would cost.

Hybrid

Revenue Requirement = Mix of Models

Many cities operate residential collection in-house (municipal) while franchising or contracting commercial collection or disposal. Rates reflect blended approach.

Example: Municipal residential collection costs + franchise commercial collection costs + contracted disposal costs, each analyzed separately.

Hybrid Delivery Models Are Common: Many cities run residential collection in-house with municipal crews but franchise or contract out commercial collection or entire disposal operations. This creates a mixed COS study: residential costs come from municipal budget, commercial from franchise/contract agreement. Rate design must account for both cost streams separately. Hybrid models offer operational flexibility — a city can control residential service quality while leveraging private-sector expertise or economies of scale for commercial or disposal services.

Emerging: Open Market & Subscription Models: A growing number of jurisdictions are moving away from exclusive franchises toward open-market models where customers can choose their waste hauler. This shifts the financial model: instead of the city rate-setting a single provider, competition sets prices. Some municipalities also experiment with subscription-based curbside service where customer volume determines what they pay. These models complicate COS study methodology because the traditional "cost per billing unit" framework breaks down when customers can switch providers or scale service dynamically.

Service Delivery Model Comparison

Aspect Municipal Franchise Contract
Who operates? City government Private exclusive operator Competitive bidders
Price basis Full cost recovery Allowable cost + profit Market bid
City control Full (direct operation) Medium (franchise terms) Low (contract terms only)
Rate predictability Medium (budget-driven) High (negotiated profit margin) High (fixed contract price)
COS methodology focus Actual budget + adjustments Allowable cost definition + audit Market benchmarking
Typical profit/margin N/A (cost recovery only) 7–15% Embedded in bid (typically 5–12%)

Key Takeaways

  • Municipal models recover 100% of documented costs; franchise models add operator profit; contract models use market competition to set price
  • COS methodology varies by model: municipal uses actual budget, franchise uses "allowable cost" definition, contract uses competitive benchmarks
  • Hybrid models — where a city operates some services while contracting others — require separate COS analysis for each service stream
  • Emerging open-market and subscription models are disrupting traditional COS frameworks by introducing customer choice and dynamic pricing

Next: Understanding where waste goes after collection is key to understanding disposal costs.

Transfer Station Operations & Economics

Transfer stations are the critical nexus in the solid waste system. They consolidate waste from collection routes, allow for material recovery and screening, and feed waste onward to disposal or processing facilities. Understanding transfer station economics is essential because they represent a major cost center whose efficiency directly impacts the revenue requirement.

Learning Objectives

  • Explain the functional role of transfer stations in the waste management system
  • Identify the key cost components of transfer station operations (facility O&M, labor, equipment, contracts)
  • Calculate and compare direct haul vs. transfer-station economics
  • Understand how transfer costs flow into the revenue requirement allocation
  • Recognize the role of regional transfer agreements and host community agreements in financial planning

Why Transfer Stations Exist

Consolidation Function

Collection vehicles (which hold 15–30 tons) dump into larger transfer trailers (typically 20–25 tons payload, constrained by the federal 80,000-lb gross vehicle weight limit). A single transfer trailer makes one long-haul trip to the landfill, replacing multiple truck trips from individual collection vehicles. This reduces long-haul fuel, labor, and equipment costs per ton.

Waste Screening & Sorting

Modern transfer stations may include scales to track tonnage, visual screening to remove hazardous or oversized items, separation of recyclables or organics if not done at curbside, and baling or compaction equipment to optimize truck space. These functions improve downstream processing efficiency and add value to collected waste.

Operational Hub

Transfer stations serve as the operational base for collection routes. Drivers start and end their shifts there, vehicles are fueled and maintained, and the facility coordinates schedules and dispatch. This centralized hub reduces idle time and improves route efficiency.

Key Cost Components

Facility O&M

Building/structure upkeep, utilities, insurance, environmental compliance, stormwater management, odor control, dust suppression.

Labor

Equipment operators (front-loaders, scales, compactors), supervisors, yard workers, administrative staff, training & development, benefits.

Equipment & Capital

Depreciation of heavy equipment, scale systems, trailers, compactors, forklifts. Repair & maintenance of equipment.

Contracts

Long-haul transport contracts (if not operated in-house), landfill tipping fees, optional material processing contracts (recycling baling, organics composting).

The Waste Cost Chain

Collection Routes Transfer Station Long-Haul Transport Landfill Disposal Route labor, fuel, vehicles Transfer ops, equipment, facility Haul labor, fuel, vehicles Tipping fee per ton

Direct Haul vs. Transfer Station Economics

A key COS decision: does it make economic sense to build a transfer station, or should collection vehicles haul directly to the landfill?

Direct Haul Scenario

Setup: Collection trucks haul directly to landfill (no transfer station).

Cost components per ton:
Collection labor + fuel
Equipment depreciation
Direct haul fuel (distance-dependent)
Landfill tipping fee

Works best when landfill is close (<30 miles) and collection volume is low.

Transfer Station Scenario

Setup: Collection trucks dump at transfer station; haul contractors move consolidated trailers to landfill.

Cost components per ton:
Collection labor + fuel
Equipment depreciation
Transfer station operations
Long-haul transport (contracted)
Landfill tipping fee

Adds transfer and long-haul costs but reduces collection vehicle drive time. Break-even point is typically 40–60 miles from landfill. High-volume systems see better economics.

Regional Transfer Agreements & Host Community Fees: Municipalities often negotiate agreements with neighboring jurisdictions or private transfer operators to use existing facilities, avoiding the capital cost of building their own. In return, they pay a negotiated per-ton fee plus tonnage-based disposal. Additionally, the jurisdiction hosting the transfer station may demand a host community benefit fee — an annual payment to offset environmental impacts. These agreements reduce capital investment but add contractual costs that must be factored into the revenue requirement.

Throughput Scaling & Capacity Planning: Transfer station economics improve with volume — fixed facility costs (rent, utilities, supervision) are spread across more tons. A facility designed for 100 tons/day has the same basic overhead whether it processes 80 or 100 tons/day, so efficiency gains come from increasing volume. Conversely, if collection volume drops (due to economic slowdown or waste reduction programs), per-ton transfer costs rise, forcing up rates. Multi-year COS projections should model volume sensitivity.

Key Takeaways

  • Transfer stations consolidate waste from collection routes into efficient long-haul trips, reducing fuel and equipment costs
  • Transfer costs include facility O&M, labor, equipment, and contracted haul/tipping services
  • Direct haul vs. transfer economics depend on landfill distance and collection volume; transfer pays off beyond 40–60 miles
  • Regional transfer agreements allow cities to avoid capital investment but introduce contractual per-ton costs
  • Transfer station costs flow into the revenue requirement as part of overall disposal cost allocation

Next: For utilities that own disposal facilities, long-term closure obligations are a critical cost element.

Landfill Closure & Post-Closure Financial Assurance

Landfills don't last forever. When a landfill reaches capacity, it must be closed in compliance with RCRA Subtitle D and state regulations. But closure is not the end of the financial obligation — post-closure care extends 30 years and beyond, requiring financial assurance mechanisms that must be funded through tipping fees. For landfill-owning utilities, these long-term obligations represent a significant portion of the revenue requirement.

Learning Objectives

  • Identify the regulatory requirements for landfill closure under RCRA Subtitle D
  • Distinguish between closure activities and post-closure care obligations
  • Explain the financial assurance mechanisms used to fund long-term landfill care
  • Understand how closure and post-closure costs enter the revenue requirement and affect tipping fees

The Two Phases of Landfill Financial Obligation

Closure Activities (Years 1–3)

Final Cover System: Cover the entire landfill surface with multi-layer engineered cap (typically 2 feet of soil, geomembrane, drainage layer, topsoil). Costs vary significantly by landfill size and site conditions.

Grading & Drainage: Slope the final surface to shed water, install perimeter controls, establish stormwater management.

Vegetation: Stabilize the cover with vegetation to prevent erosion.

Closure costs scale with landfill acreage and can represent a multi-million-dollar obligation for mid-sized facilities.

Post-Closure Care (30+ Years)

Groundwater Monitoring: Semi-annual or quarterly groundwater sampling at downgradient monitoring wells. Annual costs depend on well count and analytical requirements.

Leachate Management: Monitor and manage leachate collection system, ensure proper treatment and disposal.

Landfill Gas Monitoring: Measure methane emissions, operate gas collection/flaring systems if needed.

Post-closure care represents a significant annual cost obligation extending 30 years or more.

Detailed Closure Cost Breakdown

Final Cover Design & Engineering

Geotechnical studies, cap design, permitting, environmental review.

Material & Construction

Soil, geomembrane, drainage aggregate, haul to site, placement labor, compaction.

Stormwater & Drainage

Grading, swales, perimeter berms, retention structures, outfalls.

Vegetation & Erosion Control

Native plants, seeding, erosion blankets, slope stabilization.

Financial Assurance Mechanisms

EPA and states require proof that closure and post-closure costs will be funded. Four mechanisms are commonly used:

Trust Funds

City dedicates a reserve account funded by monthly deposits from tipping fees. Funds are segregated and managed by a trustee. Most common for municipally-owned landfills.

Advantage: Funds stay under city control. Drawback: Requires discipline to avoid raiding reserve.

Surety Bonds

Insurance company pledges to pay for closure if the landfill owner cannot. Owner pays annual premiums (typically 1–3% of total estimated closure cost per year).

Advantage: Third-party guarantee. Drawback: Ongoing premium cost; issuer may become insolvent.

Letters of Credit

Bank issues irrevocable letter of credit for closure/post-closure costs. City maintains letter as evidence of financial ability.

Advantage: Bankable guarantee. Drawback: Bank fees; requires strong credit rating.

Insurance

Liability insurance covers unforeseen closure-related costs or environmental claims (e.g., contamination discovered during closure).

Advantage: Protects against unknowns. Drawback: May not cover full closure cost.

Financial Assurance & the Revenue Requirement: Closure and post-closure costs are not optional — they are mandated by federal and state law. Landfill-owning utilities must include the present value of these costs in their revenue requirement. The calculation follows a straightforward formula: estimated closure cost + present value of annual post-closure care over 30+ years = total obligation. That total obligation is then spread over the landfill’s projected remaining life and tonnage throughput to determine a per-ton set-aside that is added to operational tipping fees.

The Uncertainty of Landfill Life & Cost Escalation: A landfill’s closure date depends on actual waste volume, which varies with population growth, economic conditions, and waste reduction programs. If waste arrives slower than projected, closure is delayed, extending the time to accumulate closure funds. Conversely, if volume exceeds projections, closure arrives sooner. Additionally, closure cost estimates prepared today may be low when closure actually occurs (inflation, regulatory changes, site conditions). COS studies should include sensitivity analysis: what if closure costs 20% more than estimated? What if closure is delayed 5 years? These scenarios affect tipping fee sufficiency.

Key Takeaways

  • Closure activities (final cap, drainage, grading) represent a multi-million-dollar obligation; must be completed within 180 days of final waste receipt
  • Post-closure care (groundwater monitoring, gas management) extends 30+ years with significant annual costs
  • Financial assurance mechanisms (trust funds, surety bonds, letters of credit, insurance) ensure funds are available when closure occurs
  • Landfill-owning utilities must include closure/post-closure costs in tipping fees; the per-ton amount depends on landfill age, size, and remaining capacity
  • Cost escalation and closure timing uncertainty require sensitivity analysis in multi-year COS projections

Next: Beyond routine collection, solid waste systems provide a range of supplemental services that need their own cost recovery.

Special Waste & Supplemental Services

Beyond routine weekly trash collection, most solid waste utilities offer or operate specialized services: bulk item pickup, yard waste programs, household hazardous waste collection, e-waste, drop-off centers. These services address specific waste streams and customer needs. In a COS study, decisions about which services to offer, how to fund them (embedded in base rates or separate fee?), and how much to charge directly affect the revenue requirement.

Learning Objectives

  • Identify common special waste categories and their cost drivers
  • Explain the difference between embedded and separate-fee funding for supplemental services
  • Determine whether to include special services in base rates or offer as optional, paid services
  • Understand cost and participation drivers for HHW, e-waste, and C&D programs

Common Special Waste & Supplemental Services

Bulky/Large Item Collection

What it includes: Furniture, appliances, mattresses, large items that don’t fit in carts.

Cost drivers: Collection labor is high (manual handling), disposal cost is variable (some items have salvage value, others are landfilled).

Funding: Often embedded in base rates for a limited number of pickups per year, or offered as a per-pickup fee.

Yard Waste & Organics

What it includes: Leaves, grass clippings, branches, food waste (where mandated).

Cost drivers: Collection costs plus composting or processing fees. Growing cost pressure from SB 1383 and similar organics diversion mandates.

Funding: May be embedded in base rates, offered as optional service, or mandated with a separate monthly fee.

Household Hazardous Waste (HHW)

What it includes: Paint, batteries, electronics, chemicals, oils, pesticides.

Cost drivers: Specialized handling and disposal make HHW one of the most expensive per-household service categories. Often limited to 1–2 collection events per year or permanent drop-off facility. HHW cannot go to landfill.

Funding: Almost always funded separately via city general fund or HHW collection fees. Not embedded in base trash rate.

Construction & Demolition Debris

What it includes: Lumber, drywall, concrete, metals, roofing from construction/remodeling.

Cost drivers: Disposal costs are often higher per ton than MSW due to specialized handling and markets for separated materials.

Funding: Usually a separate per-load fee at drop-off. Often not part of residential utility rates.

Drop-Off/Convenience Centers

What it includes: Self-haul facilities where residents drop off trash, recycling, yard waste, bulky items, C&D, e-waste.

Cost drivers: Staff, equipment, and tipping fees represent a significant annual operating budget. Participation is optional; generates revenue from fees.

Funding: Usually per-load fee to recover operating and disposal costs, or free/low-cost with embedded cost in base rates.

E-Waste / Electronics Recycling

What it includes: Computers, monitors, TVs, phones, printers — materials containing precious metals, glass, and hazardous substances.

Cost drivers: Varies widely by device type and market for recovered materials. Some manufacturers (via take-back programs) absorb cost; others require collection fees.

Funding: Often free to residents via manufacturer take-back programs or city-organized collection events. When funded locally, typically a per-unit fee or free through convenience center.

Household Hazardous Waste Programs — Cost Per Household Served: HHW collection is essential for environmental protection but expensive. Typical participation rates for quarterly collection events are 10–15% of households served. Event costs include facility rental, staff, equipment, transportation, and disposal. When spread across all households (not just participants), the per-household cost is modest, but the per-participant cost is substantial. Permanent drop-off facilities cost more to operate annually but offer year-round access and improve participation rates.

Construction & Demolition Debris Pricing & Tipping Fee Disparity: C&D tipping fees are typically higher per ton than MSW because of sorting/processing requirements and market volatility for recovered materials (metals, wood). Some C&D processors operate at break-even or loss depending on commodity markets. When a city operates or contracts a C&D drop-off, it must budget for landfill/transfer tipping and processing overhead. Per-load fees must be set to recover costs across expected volume levels, with margin built in for volume fluctuations.

E-Waste & Manufacturer Take-Back Programs

Federal and state laws increasingly require manufacturers (not municipalities) to fund the end-of-life management of electronics they produce. Many manufacturers operate take-back programs: customers mail devices to the manufacturer or visit retail partners for free recycling. This shifts e-waste cost from municipalities to producers. However, non-participating manufacturers and customer convenience concerns keep many cities offering local e-waste collection. COS studies should account for manufacturer program participation rates — if 60% of e-waste is handled via manufacturer take-back, only 40% becomes a municipal cost.

Key Takeaways

  • Special waste services (HHW, bulky items, organics, C&D) address specific waste streams with high handling costs
  • Decisions to embed these services in base rates vs. charge separate fees directly affect the revenue requirement and rate structure
  • HHW collection is mandated for environmental/safety reasons but is one of the most expensive per-household services; often funded outside the solid waste utility
  • C&D tipping fees typically exceed MSW fees; C&D programs require careful cost analysis to ensure fee adequacy
  • E-waste programs are increasingly supplemented by manufacturer take-back programs; municipal COS should account for program participation rates

Next: Operational data from the field drives the accuracy of every allocation in the COS study.

Route Optimization & Operational Data

Costs don’t appear out of thin air. They are driven by operational realities: how many stops are on a route, how long does each stop take, how much waste is collected per route, what is the utilization of the truck? These metrics are the foundation of collection cost allocation in the COS study. Reliable operational data is critical for building defensible cost estimates and ensuring rates are neither too high nor too low.

Learning Objectives

  • Identify key operational metrics: stops per route, time per stop, tons per route, vehicle utilization
  • Explain how operational data drives collection cost allocation to residential, commercial, and other service categories
  • Distinguish cost differences between automated side-load, semi-automated, and manual rear-load collection methods
  • Understand route efficiency analysis and the relationship between route data and rates

Five Key Operational Metrics

Stops Per Route

How many collection points (homes or businesses) does a truck service per shift? Typical: 200–400 residential stops, 40–80 commercial stops per route.

Implication: More stops/route = lower cost per stop.

Time Per Stop

Minutes to service one location. Residential: 0.75–1.5 min/stop (varies with automation). Commercial: 3–8 min/stop (more variable).

Implication: Faster stops = more stops/route = better utilization.

Tons Per Route

Total material collected per truck per shift. Typical: 12–16 tons/route for residential, 8–15 for commercial.

Implication: More tons/route = fewer routes needed.

Vehicle Utilization

Percentage of truck capacity actually used. If truck holds 20 tons and typical route is 14 tons, utilization = 70%.

Implication: Low utilization (<60%) signals opportunity to consolidate routes or resize fleet.

Cost Per Stop

Total collection cost ÷ stops serviced. Includes labor, fuel, vehicle overhead, supervision.

Implication: Lower cost/stop = better efficiency = defensible rates.

Cost Per Ton

Total collection cost ÷ tons collected. Varies significantly by service type, geography, and operational efficiency.

Implication: Benchmark against peer systems; if higher, investigate inefficiency.

How Operational Data Is Collected

GPS & Telematics

Modern collection trucks equipped with GPS log every movement: stops, dwell time, idle time, speed. Telematics systems track fuel consumption, engine performance, driver behavior. Data feeds into route analysis software showing stop counts, times, and efficiency metrics in real time.

Cost: Modest per-truck annual investment for hardware + software. Benefit: Precise data, real-time optimization.

Time Studies

Dedicated observer rides routes and manually records time per stop, delays, system breakdowns. Typically 5–10 routes are sampled across different geographies (urban, suburban, rural) and service types (residential, commercial).

Cost: Moderate one-time investment for comprehensive study. Benefit: Detailed, validated data.

Stop Counts & Route Analysis

Manual or system-based count of collection points per route. Combined with billing system data (how many accounts per route) to cross-check accuracy. Reveals routes that are understaffed vs. overstuffed.

Cost: Low (internal staff). Benefit: Quick assessment of route balance.

Tonnage Tracking

Scale house records at transfer stations or landfills show total tonnage by route or day. When matched with customer accounts and billing data, reveals tons per account, tons per route, density patterns by geography.

Cost: Minimal (existing infrastructure). Benefit: Validates tons/stop and capacity utilization.

Collection Method Cost Comparison

Equipment choice directly impacts labor and efficiency:

Automated Side-Load (ASL)

Hydraulic arm on truck grabs and empties cart from curbside. One operator, minimal labor per stop.

Time per stop: 0.6–0.9 min (fastest)

Labor cost: Low (single operator)

Equipment cost: Higher truck cost plus higher maintenance due to hydraulic arm complexity

Best for: Dense urban/suburban areas with uniform carts.

Manual Rear-Load

Two workers manually dump cans into truck hopper. Labor-intensive but flexible and lower equipment cost.

Time per stop: 1.2–2.0 min (slower)

Labor cost: High (driver + helper = roughly 2x the labor cost of automated)

Equipment cost: Lower truck cost and simpler maintenance

Best for: Rural areas, variable cart types, uphill terrain.

Route Efficiency & Right-Sizing: A well-balanced route operates at 80–90% of truck capacity. When route data shows trucks operating at <70% capacity, it signals overstaffing — the system can consolidate routes and reduce crew count. Conversely, when routes regularly exceed 90% capacity, overloading occurs, forcing second trips or skipped collections. The solution: data-driven route redesign. Many utilities discover that 10–15% of routes are inefficiently configured and can be rebalanced without service cuts. This translates directly to lower cost per stop and therefore lower rates.

Automation Cost Trade-Off: Automated side-load equipment can cut time per stop roughly in half — a significant productivity gain. However, automated trucks have higher capital costs. The break-even depends on route density: higher-density routes (more stops per shift) justify the equipment investment through labor savings, while lower-density routes may be more cost-effective with manual collection. COS studies should analyze the optimal collection method mix for different geography types by comparing labor savings against incremental equipment and maintenance costs.

Key Takeaways

  • Operational metrics (stops/route, time/stop, tons/route, utilization) are the foundation of collection cost allocation
  • GPS/telematics, time studies, and stop counts provide data to validate and improve route efficiency
  • Automated side-load is fastest per stop but most capital-intensive; manual rear-load is slower but more flexible and cheaper
  • Route optimization typically uncovers 10–15% efficiency gains by rebalancing and rightsizing routes
  • Cost per stop and cost per ton metrics allow benchmarking against peer systems and identification of efficiency opportunities

Next: Solid waste rates must navigate regulatory requirements and public process.

Regulatory & Public Process

A COS study is a technical product, but rates are a policy decision. Cities and counties must follow state law, federal regulations, and local processes to set legally defensible rates. Understanding the regulatory landscape and public hearing requirements is essential for anyone guiding a rate-setting process. A technically perfect COS study can fail if the legal and political process is mishandled.

Learning Objectives

  • Identify key regulatory requirements for rate-setting in your state and locality
  • Navigate public hearing and notice requirements
  • Understand Proposition 218 and similar state-level rate approval constraints
  • Develop a communication strategy to translate COS findings into plain language for council and public

Regulatory Frameworks for Rate-Setting

State Regulatory Frameworks

Government-Owned Utilities: Most states require public notice and hearing before rates are raised, but approval process is simpler than investor-owned utilities. Governing body (city council, county commissioners) sets rates based on findings presented in study.

Investor-Owned/Private Utilities: Many states require Public Utility Commission (PUC) approval. PUC reviews cost justification, may hold hearings, may allow rate-of-return regulation (fixed profit margin).

Public Hearing & Notice Requirements

Advance Notice: Most states require 7–30 days written notice to all affected ratepayers before hearing. Notice must include proposed rate schedule, reason for increase, date/time of hearing.

Hearing Format: Public hearing where customers can comment. City must respond to public comments (can be in writing or at follow-up session).

Record & Findings: City must document the record, including COS study, public comments, and council findings justifying the rates.

Rate Protest Procedures

Protest Threshold: Varies by state. California Prop 218 (for most jurisdictions) requires majority protest (>50% of affected customers by account count) to block rates. Other states allow rate protests but do not necessarily require majority threshold to continue process.

Protest Hearing: If threshold is met, city must hold additional hearing to consider protests. Can result in rate adjustment or reaffirmation of original proposal.

Government-Owned vs. Investor-Owned Rate Setting

Government-Owned Utility (Most Common)

Authority: City or county ordinance sets rates. City council votes to approve.

Process: COS study → staff recommendation → public hearing → council vote.

Legal basis: State law requires due process (notice & hearing) but typically no PUC review.

Implication: City has flexibility to adjust rates, but must follow public process & be prepared to defend in court if challenged.

Investor-Owned/Private Utility

Authority: PUC (Public Utility Commission) sets rates. May require rate-of-return regulation (fixed % profit margin).

Process: COS study → filing with PUC → PUC review & hearings → order approving rates.

Legal basis: State statute granting PUC authority to regulate investor-owned utilities.

Implication: More regulatory scrutiny but also more predictability. PUC precedent guides rate design.

Proposition 218 (California) & Similar State Statutes: California’s Prop 218 (1996) established one of the nation’s strictest rate approval processes: utilities must provide written notice to all affected properties, hold a public hearing, and secure majority approval from property owners/customers (by count, not by dollar). A single property owner who represents >50% of affected properties can protest and block a rate increase. Many other states have adopted similar frameworks. For COS studies in Prop 218 jurisdictions, the study must be exceptionally clear and defensible because the bar for customer approval is high. Cities must be prepared to clearly explain the “why” behind rates, not just the “what”.

Public Communication Strategy

A strong public communication plan translates technical COS findings into language that council members and customers understand:

Executive Summary Document

5–10 page plain-language summary: what is a COS study, why this city needs a rate increase, what happens to the money, what the new rates are, timeline for implementation. Use charts, not tables. Avoid jargon.

Council Presentation

Visual presentation showing: current cost drivers, comparison to peer cities, consequences of not raising rates (service reductions, infrastructure decay), proposed rate schedule, phasing plan. Q&A prepared for anticipated objections.

Public Hearing Preparation

Anticipate common questions: “Why do rates have to go up?” “Are we wasting money?” “Is the study biased?” Prepare clear, concise answers. Have staff present findings, not consultants (builds trust).

FAQ & Website Content

Post study findings, rate tables, FAQs, and bill impact examples on city website. Make the study accessible: not buried in a 200-page technical document, but linked from prominent location with plain-language summary.

Key Takeaways

  • Government-owned utilities follow public notice/hearing/council vote process; investor-owned utilities require PUC approval and rate-of-return regulation
  • State laws (including Prop 218-type statutes) may impose strict notice and approval thresholds; COS study must be exceptionally defensible
  • Rate protests, if meeting threshold, trigger additional hearing and possible adjustment
  • Public communication strategy — executive summary, council presentation, FAQ, website — is as important as the technical study itself
  • City staff and council members must be prepared to explain the “why” behind rates in plain language, not technical terms

Next: Looking beyond traditional budgeting, full cost accounting provides a comprehensive view of true service costs.

Full Cost Accounting

A traditional COS study captures current operating costs: collection, disposal, recycling, administration. But it often misses past costs and future costs. Full Cost Accounting (FCA), a framework promoted by EPA and sustainability advocates, expands the lens to include historic environmental liabilities, future post-closure obligations, and environmental externalities. For many utilities, FCA reveals that customers are paying less than the true total cost of waste service.

Learning Objectives

  • Define full cost accounting and explain how it differs from traditional budgeting and COS methodology
  • Identify and quantify past costs (closure of old facilities, legacy environmental cleanup)
  • Recognize present costs (current operations) as captured in the traditional COS
  • Project future costs (post-closure care, equipment replacement, capacity planning)
  • Understand the concept of hidden subsidies and how FCA reveals who actually pays for waste service

The Three Layers of Full Cost Accounting

Full Cost Accounting Framework PAST COSTS Closure of old landfills (final cover, caps, closure care), remediation of contaminated sites Environmental cleanup from past practices, legacy debt from prior decades PRESENT COSTS (Current Operations) Collection labor, vehicles, fuel — captured in traditional COS Disposal (landfill tipping fees, transfer station ops), recycling processing, administration This is what the standard COS study measures FUTURE COSTS Post-closure care of current landfills (30+ years of groundwater monitoring, leachate management) Equipment replacement (fleet turnover in 10–15 years), capacity expansion, climate adaptation TOTAL COST OF SERVICE = SUM OF ALL THREE LAYERS

Detailed Cost Component Breakdown

Past Costs

Old landfill closure: Final capping, drainage, vegetation of closed facility. Costs scale with acreage and site complexity.

Environmental remediation: Cleanup of contaminated groundwater, soil from historical disposal practices. Costs vary enormously by site conditions.

Legacy debt: Bonds issued in prior years to fund infrastructure, still being repaid.

These costs appear as ongoing annual debt service or one-time cleanup project expenditures.

Present Costs

Collection: Labor, vehicles, fuel, maintenance — typically the largest cost category.

Disposal: Landfill tipping fees, transfer station operations.

Administration: Staff, utilities, equipment, overhead.

This is the standard COS — what traditional rate studies measure.

Future Costs

Post-closure care: 30-year obligation for groundwater monitoring, leachate management, gas monitoring — significant annual costs.

Equipment replacement: Fleet trucks depreciate over 10–15 years; reserve funding must match the replacement cycle.

Capacity expansion: New landfill or expanded transfer facility projected in 10–20 years — a major capital project.

Present-value analysis captures these long-term obligations, which often dwarf annual operating costs.

Hidden Subsidies & Who Really Pays: Many solid waste utilities are funded partially by general fund or property tax subsidy, in addition to solid waste rates. When this occurs, customers are not paying the full cost of service — taxpayers are subsidizing waste collection. FCA framework makes this visible: if total full-cost obligations exceed rate revenue, the gap is being subsidized by the city general fund. This cross-subsidy may be intentional policy (city council decides waste service is a public good worthy of tax support) or unintentional (city hasn’t updated rates to reflect true cost). FCA study should calculate and disclose the subsidy amount so council can make informed decisions about whether it’s sustainable long-term.

Environmental Externalities & Unpriced Costs: While FCA focuses on monetary costs, it also provides framework for disclosing environmental impacts not fully captured in rates. Landfills generate greenhouse gases (methane, CO2 from decomposition and equipment); leachate poses groundwater contamination risk; collection vehicles emit particulates and NOx. Some FCA frameworks calculate monetized environmental cost (e.g., social cost of carbon) and disclose alongside traditional rate cost. This is not required by law but provides transparency: customers can see that waste management has hidden environmental costs that may not be reflected in the rate they pay. As climate and environmental regulations tighten, more cities are adopting FCA-style disclosure.

Full Cost Accounting in Practice

Illustrative framework showing how costs are layered in a full cost accounting analysis:

Cost Category Illustrative Share of Full Cost Typically Funded By
PAST COSTS
Old landfill closure (ongoing) ~3–5% General fund or rates
PRESENT COSTS
Collection labor, vehicles, fuel ~45–50% Waste rates (primary)
Disposal (tipping + transfer) ~18–22% Waste rates
Administration ~8–12% Waste rates
FUTURE COSTS (Annual Reserve Accrual)
Post-closure financial assurance ~10–14% Waste rates (tipping fee component)
Equipment replacement reserve ~6–10% Waste rates
TOTAL FULL COST 100%

When current rates recover less than 100% of full cost, the gap is funded by general fund subsidy or deferred to future ratepayers. FCA makes the size of this gap transparent to decision-makers.

Key Takeaways

  • Full Cost Accounting includes past costs (closure, remediation), present costs (current operations), and future costs (post-closure, equipment replacement)
  • Traditional COS typically captures only present costs; FCA reveals hidden past and future obligations
  • Hidden subsidies occur when rates do not recover full costs and general fund or property tax fills the gap
  • Environmental externalities (greenhouse gas emissions, groundwater contamination risk) can be disclosed alongside traditional monetary costs
  • FCA framework provides transparency about true total cost of waste service, helping councils make informed policy decisions about subsidies and rate adequacy
