Section 18797.3 - Adjustment Method Calculation
Current through Register 2024 Notice Reg. No. 38, September 20, 2024
(a) If a jurisdiction is a region, then the tonnage amounts, and adjustment factor number for all cities and unincorporated counties included in the region's regional agreement, shall be summed before calculating the single adjustment for the region's base-year generation.
(b) Before calculating the adjustment, a jurisdiction shall separate the base-year generation tonnage by source into residential and non-residential amounts. If a jurisdiction cannot derive the actual residential and non-residential amounts from its records, the jurisdiction may make a best estimate of how much of their base-year generation is from residential sources and how much is from non-residential sources.
(c) When calculating the values in subdivision (e) of this section, and calculating the adjusted base-year generation tonnage in subdivision (f) of this section, a jurisdiction shall use the values defined below:
| RWGB | = | Base-Year Residential Waste Generation in Tons | |
| NRWGB | = | Base-Year Non-Residential Waste Generation in Tons | |
| PR | = | Reporting-Year Population in Persons | |
| PB | = | Base-Year Population in Persons | |
| ERLF | = | Reporting-Year Labor Force Employment in Jobs | |
| ERIN | = | Reporting-Year Industry Employment in Jobs | |
| EBLF | = | Base-Year Labor Force Employment in Jobs | |
| EBIN | = | Base-Year Industry Employment in Jobs | |
| TR | = | Reporting-Year Taxable Sales in Dollars | |
| TB | = | Base-Year Taxable Sales in Dollars | |
| CPIR | = | Reporting-Year Consumer Price Index | |
| CPIB | = | Base-Year Consumer Price Index |
For example, in the hypothetical jurisdiction of "Surfcity":
| RWGB | = | 15,000 tons | |
| NRWGB | = | 20,000 tons | |
| PR | = | 12,000 persons | |
| PB | = | 10,000 persons | |
| ERLF | = | 6,000 jobs | |
| EBLF | = | 5,500 jobs | |
| TR | = | 3,100,000 dollars | |
| TB | = | 3,000,000 dollars | |
| CPIR | = | 154.0 | |
| CPIB | = | 130.7 |
(d) Before calculating values other than those described in section 18797.2(b) for the equations in subdivision (e) of this section, a jurisdiction shall select one of three countywide employment factor number sets:
(e) Before performing the adjustment calculation, a jurisdiction shall calculate values for the four equations below:
| (1) | IM | = | Inflation Multiplier: |
| CPIB | |||
| CPIR | |||
| Example: | |||
| IM | = | 130.7 | |
| 154.0 | |||
| = | 0.8487 | ||
| (2) | CTR | = | Corrected Reporting-Year Taxable Sales in Dollars: |
| TR x IM | |||
| Example: | |||
| CTR | = | 3,100,000 x 0.8487 | |
| = | 2,630,970 |
| (3) | NRAF = | Non-Residential Adjustment Factor: | ||
| (ER / EB) + (CTR / TB) | ||||
| 2 | ||||
| Example 3a: | Use Labor Force Employment in NRAF | |||
| NRAFLF = | (6,000/5,500) + (2,630,970/3,000,000) | |||
| 2 | ||||
| = | 0.984 | |||
| Example 3b: | Use Industry Employment in NRAF | |||
| NRAFIN = | (4,500/3,950) + (2,630,970/3,000,000) | |||
| 2 | ||||
| = | 1.008 | |||
| (4) | RAF = | Residential Adjustment Factor: | ||
| (PR / PB) + NRAF | ||||
| 2 | ||||
| Example 4a: | Use NRAFLF | |||
| RAFLF = | (12,000/10,000) + 0.984 | |||
| 2 | ||||
| = | 1.092 | |||
| Example 4b: | Use NRAFIN | |||
| RAFIN = | (12,000/10,000) + 1.008 | |||
| 2 | ||||
| = | 1.104 | |||
(f) Using the variables defined in subdivisions (c) and (e) of this section, a jurisdiction shall calculate the adjusted base-year generation tonnage using the equation below:
| ERYG | = | Estimated Reporting-Year Generation: | ||
| (RWGB x RAF) + (NRWGB x NRAF) | ||||
| Example 1: | Use RAFLF and NRAFLF | |||
| ERYG | = | (RWGB x RAFLF) + (NRWGB x NRAFLF) | ||
| = | (15,000 x 1.092) + (20,000 x 0.984) | |||
| = | 36,060 tons | |||
| Example 2: | Use RAFIN and NRAFIN | |||
| ERYG | = | (RWGB x RAFIN) + (NRWGB x NRAFIN) | ||
| = | (15,000 x 1.104) + (20,000 x 1.008) | |||
| = | 36,720 tons | |||
| Example 3: | Use RAFLF and NRAFIN | |||
| ERYG | = | (RWGB x RAFLF) + (NRWGB x NRAFIN) | ||
| = | (15,000 x 1.092) + (20,000 x 1.008) | |||
| = | 36,540 tons | |||
