Current through Register Vol. 41, No. 9, December 16, 2024

Section 9VAC20-81-340 - Operation requirements

The operation of all compost facilities, solid waste transfer stations, centralized waste treatment facilities, materials recovery facilities, waste to energy and incineration facilities, and waste piles shall be governed by the standards as set forth in this section. Operations for these facilities will be detailed in an operations manual that shall be maintained in the operating record in accordance with 9VAC20-81-485. This operations manual will include an operations plan, an inspection plan, a health and safety plan, an unauthorized waste control plan, and an emergency contingency plan meeting the requirements of this section and 9VAC20-81-485. This manual shall be made available to the department when requested. If the applicable standards of this chapter and the facility's operations manual conflict, this chapter shall take precedence.

A. Compost facilities.

1. For facilities that will compost only Category I wastes:

a. Noncompostable or other undesirable solid waste shall be segregated from the material to be composted. Solid waste that is not composted, salvaged, reused, or sold must be disposed at a permitted solid waste management facility authorized to accept the waste.

b. The addition of any other solid waste including but not limited to hazardous waste, regulated medical waste, construction waste, debris, demolition waste, industrial waste, or other municipal solid waste to the Category I waste received at the composting facility is prohibited, except that the materials that are excluded under 9VAC20-81-95 may be combined with Category I waste for the purpose of producing compost under the provisions of this chapter.

c. Access to the composting facility shall be permitted only when an attendant is on duty.

d. Dust, odors, and vectors shall be controlled so they do not constitute nuisances or hazards. Fugitive dust and mud deposits on main offsite roads and access roads shall be minimized at all times to limit nuisances. Dust shall be controlled to meet the requirements of Article 1 (9VAC5-40-60 et seq.) of Part II of 9VAC5-60.

e. The owner or operator shall prepare, implement, and enforce a safety program and a fire prevention and suppression program designed to minimize hazards.

f. Open burning shall be prohibited on the facility property.

g. Leachate or other runoff from the facility shall not be permitted to drain or discharge directly into surface waters, unless authorized by a VPDES permit.

h. Designed buffer zones shall be maintained.

2. Facilities for the composting of Category II, III, or IV feedstocks, including those that mix these categories with Category I feedstocks, shall be provided with:

b. Products will continue to be considered as solid wastes until the testing indicates that they attain finished compost standards. Samples and measurements taken for the purpose of monitoring shall be representative of the monitored activity and shall be conducted in a manner consistent with SW-846, as amended, and other applicable standards. The minimum number of samples that shall be collected and analyzed is shown in the table below. Samples to be analyzed for metals shall be composited prior to the analysis.

	Minimum Frequency of Analysis
	Amount of finished compost¹(tons per 365 day period)	Frequency²
	Less than 320	Once per year.
	Equal to or greater than 320 but less than 1,653	Once per quarter (four times per year).
	Equal to or greater than 1,653 but less than 16,535	Once per 60 days (six times per year).
	Equal to or greater than 16,535	Once per month (12 times per year).
	¹Either the amount of finished compost applied to the land or prepared for sale or give-away for application to the land (dry weight basis).
	²After the finished compost has been monitored for two years at the frequency in the above table, the facility may request that the department reduce the frequency of monitoring.

c. All finished products will be tested for compost stability using one of the methods listed below:

(1) Temperature decline to near ambient conditions when not the result of improper management of the composting process. Composting records shall indicate schedules for turning, monitoring of moisture within the required range, and mix of composting feedstocks.

(2) Reheat potential using the Dewar Compost Self-Heating Flask. The results must indicate a stable product. Temperature rise above ambient must not exceed 10°C for stable compost. Very stable compost will not exceed 20°C above ambient.

(3) Specific oxygen uptake. To be classified as stable the product must have a specific oxygen uptake rate of less than 0.1 milligrams per gram of dry solids per hour.

(4) SolvitaTM Compost Maturity Test. To be classified as stable the product must exhibit color equal or greater than six.

(5) Carbon dioxide evolution. To be classified as stable the product must not evolve more than 1,000 milligrams of carbon dioxide per liter per day.

d. In addition to testing required of this subsection, finished products produced from any Category III and IV materials will be tested for the presence of the following organisms using the methods indicated below:

(1) Parasites. The density of viable helminth ova in the finished compost shall be less than one per four grams of total solids (dry weight basis) at the time the finished compost is prepared for sale or give away in a container for application to the land. Viable helminth ova reduction shall be demonstrated by testing the finished compost once per quarter for a period of one year. After the viable helminth ova reduction has been demonstrated for the composting process, additional helminth ova testing will not be required provided the composting operating parameters and incoming waste stream are consistent with the values or ranges of values documented during the initial helminth ova reduction demonstration. If the composting parameters or incoming waste stream change a new viable helminth ova reduction demonstration is required, and

(2) Bacteria pathogens. Either the density of fecal coliform in the finished compost shall be less than 1000 Most Probable Number (MPN) per gram of total solids (dry weight basis), or the density of Salmonella sp. bacteria in the finished compost shall be less than three MPN per four grams of total solids (dry weight basis) at the time the finished compost is prepared for sale or give away in a container for application to the land.

(3) Other test methods, or facility operating standards may be used in lieu of the above parasite and pathogen testing requirements as approved by the department.

e. Metals. In addition to the testing requirements contained in this subsection, all finished products produced from Category IV materials shall be analyzed for the metals shown below. The concentration of contaminants shall not exceed the following levels:

	Metal	Concentration, mg/kg dry solids
	Arsenic	41
