Vector Attraction Reduction
1 One of the following vector attraction reduction processes is required for Class A biosolids or Class B biosolids used to produce biosolids growing medium:
(a) a digestion process (aerobic or anaerobic) resulting in the mass of volatile solids of the biosolids being reduced by more than 38 per cent;
(b) when the 38 per cent volatile solids reduction requirement in paragraph (a) cannot be met for an aerobically digested biosolids, vector attraction reduction can be demonstrated by digesting a portion of the previously digested biosolids that has a per cent solids of two per cent or less aerobically in the laboratory in a bench-scale unit for 30 additional days at 20 Celsius. When, at the end of the 30 days, the volatile solids in the biosolids at the beginning of that period is reduced by less than 15 per cent, vector attraction reduction is achieved;
(c) when the 38 per cent volatile solids reduction requirement in paragraph (a) cannot be met for an anaerobically digested biosolids, vector attraction reduction can be demonstrated by digesting a portion of the previously digested biosolids anaerobically in the laboratory in a bench-scale unit for 40 additional days at a temperature between 30 and 37 Celsius. When, at the end of the 40 days, the volatile solids in the biosolids at the beginning of that period is reduced by less than 17 per cent, vector attraction reduction is achieved;
(d) the specific oxygen uptake rate (SOUR) for biosolids treated in an aerobic process shall be less than or equal to 1.5 milligrams of oxygen per hour per gram of total solids (dry weight basis) at a temperature of 20 Celsius;
(e) the pH of biosolids shall be raised to 12 or higher by alkali addition and, without the addition of more alkali, shall remain at 12 or higher for two hours and then at 11.5 or higher for an additional 22 hours;
(f) the per cent solids of biosolids generated in a wastewater treatment process must be equal to or greater than 90 per cent based on the moisture content and total solids prior to mixing with other materials. The biosolids must thereafter be managed in such a way that the moisture content of the biosolids does not increase such that compliance with the 90 per cent solids requirement is maintained until such time as the biosolids is land applied in accordance with section 7 (2) or distributed in accordance with 7 (4) of this regulation.

After the vector attraction reduction process is completed the carbon to nitrogen ratio of the compost must be greater than or equal to 15:1 and less than or equal to 35:1;
(b) Class A compost must be retained in curing piles for at least 21 days. After the 21 day period, the carbon to nitrogen ratio of the Class A compost must be greater than or equal to 15:1 and less than or equal to 35:1 and must not re-heat, upon standing, under the following conditions:
(i) compost is aerated and formed into a pile no smaller than 3 metres in diameter and 2 metres high with compost having a moisture content between 35 per cent and 60 per cent;

Notes
1 All values in g/g unless otherwise stated. Substances must be analyzed using methods specified in protocols approved under section 53 of the Contaminated Sites Regulation, B.C. Reg. 375/96, or alternate methods acceptable to the director.
2 The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.
3 Intake pathway of exposure modeled is inadvertent ingestion of soil.
4 The pH is the pH of the soil at a site.
5 Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 74.0 g/g.
6 Standard is applicable to livestock other than sheep. Consult director for further advice.
7 NS — no standard. Insufficient acceptable scientific data exists, so no standard is calculated.

Schedule 11
Requirements for Biosolids Growing Medium
1 Biosolids growing medium must be derived from either Class A biosolids or Class B biosolids that meet the pathogen and vector attraction reduction requirements for Class A biosolids specified in Schedules 1, 2, and 3.
2 The following standards for biosolids growing medium must be met:
(a) substance concentrations, listed in Schedule 4, Column 2;
(b) Total Kjeldahl Nitrogen (TKN) < 0.6 per cent by weight;
(c) carbon to nitrogen ratio, (C:N) ratio must be > 15:1;
(d) organic matter content must not exceed 15 per cent dry weight.
Schedule 12
Organic Matter Suitable for Composting
1 Only the organic matter in the following table may be composted into Class A compost or Class B compost:
Column 1 — Organic Matter | Column 2 — Constituents of Organic Matter |
animal bedding | animal bedding derived from straw, paper, hog fuel, wood chips, bark, shavings or sawdust. |
biosolids | stabilized municipal sewage sludge resulting from a municipal waste water treatment process or septage treatment process which has been sufficiently treated to reduce pathogen densities and vector attraction to allow the sludge to be beneficially recycled in accordance with the requirements of this regulation. |
brewery waste/winery waste | used or diverted grain, malt, hop flowers, berries, fruit, leaves and twigs and yeast resulting from brewing or wine making process. |
domestic septic tank sludge | sludge removed from a septic tank used for receiving, treating and settling domestic sewage. |
fish wastes | fish carcasses and parts from harvested wild stocks, commercial aquaculture operations and fish processing facilities. This would include offal, viscera and mortalities from fish and shellfish. It would also include faeces captured from commercial aquaculture net pens. |
food waste | recyclable food for humans that has been diverted from residential, commercial or institutional sources. |
hatchery waste | broken or unhatched eggs, unhatched chicks, membranes, embryonic fluids and eggshell. |
manure | animal excreta from pets, animals in zoological facilities, fish held in commercial aquaculture or aquarium facilities, livestock, farmed game or poultry, this does not include the management of animal excreta (manure) on farms as defined as agricultural waste in B.C. Reg. 131/92 but does include animal excreta (manure) not included within the scope of B.C. Reg. 131/92. |
milk processing waste | sludge or biomass from treatment of milk or fluid milk which has been diverted from human food consumption. |
plant matter derived from processing plants | fruit, vegetable and vegetative material derived from fruit and vegetable processing plants, these are materials which have been removed from an agricultural operation and no longer fit within the definition of agricultural waste (agricultural vegetation waste) as defined in B.C. Reg. 131/92. |
poultry carcasses | carcasses of domestic fowls, such as chickens, turkeys, ducks or geese, raised for meat or eggs. This would include offal and viscera as well as mortalities from fowl which died from reported "Federally Reported Diseases". |
untreated and unprocessed wood residuals | clean (non-contaminated and untreated) wood from lumber manufacture, e.g. shavings, sawdust, chips, hog fuel, ground mill ends and land clearing waste which has been ground with the majority of the greenery removed and no soil present but does not include construction and demolition debris. |
whey | the serum or watery part of milk that remains after the manufacture of cheese. |
yard waste | clean and untreated wood waste or non-food vegetative matter resulting from gardening operations, landscaping, and land clearing; yard waste does not include wood waste derived from construction or demolition. Neither human or animal food waste that is diverted from residential, commercial or institutional sources, nor manure, is yard waste. |
