Interpretation

1  (1) In this regulation:

"Act" means the Environmental Management Act;

"ADt" means an air dry tonne of pulp product where the weight of the pulp product is corrected to reflect the weight that the pulp product would be if the pulp were composed of 10% water and 90% fibre;

"AOX" means halogenated organic compounds that are adsorbable by activated carbon;

"CBPROD" means, subject to subsection (2), the 90th percentile of the daily production rate of bleached pulp produced from an on-site bleach plant with the use of chlorine or chlorine compounds, or both chlorine and chlorine compounds, expressed as ADt, determined by the use of statistical methods, and using a period of time approved by a director for determination of the 90th percentile of the rate of chlorine or chlorine compound bleached pulp production;

"compliance sampling method" means the technique used to collect samples which are subsequently analyzed to determine if the effluent satisfies the quality standards established under sections 2, 3 and 6;

"EFF" means, subject to subsection (2), the 90th percentile of the rate of effluent, expressed as m3/day, including any sanitary effluent combined with process effluent, discharged from a pulp or paper or pulp and paper mill, determined by the use of statistical methods, and using a period of time approved by a director for determination of the 90th percentile of the rate of discharge of effluent;

"permittee" means a person who holds a permit issued under section 14 of the Act;

"phase I" means a compliance sampling period commencing on the date this regulation comes into force and expiring on the date that phase II commences;

"phase II" means a compliance sampling period commencing on a date specified in writing by the director;

"PROD" means, subject to subsection (2), the 90th percentile of the daily production rate of a pulp or paper or pulp and paper mill, expressed as ADt, determined by the use of statistical methods, and using a period of time approved by a director for determination of the 90th percentile of the rate of production;

"96 h LC50 toxicity" means the calculated concentration of effluent that is lethal to 50% of the test fish (rainbow trout (Oncorhynchus mykiss)) during a 96 hour exposure.

(2) If there is an insufficient number of days of production to perform a valid 90th percentile calculation of CBPROD, EFF or PROD, the director may use the mill's chlorine or chlorine compound bleached pulp production design figure, effluent flow design figure or production design figure respectively as values for CBPROD, EFF or PROD until such time as these parameters may be calculated in accordance with subsection (1).

Prohibitions

2  (1) A permittee that operates a bleached kraft pulp mill that uses chlorine or chlorine compounds to bleach the pulp shall not discharge effluent into the environment if the amount of AOX in the effluent exceeds the lesser of

(a) a monthly average of 0.6 kg of AOX/ADt of pulp produced in the bleach plant, or

(b) the maximum AOX discharge rate, expressed in kg/ADt, authorized by a permit issued under section 14 of the Act.

(1.1) A permittee that operates a bleached sulphite pulp mill or pulp and paper mill that uses chlorine or chlorine compounds to bleach the pulp shall not discharge effluent into the environment if the amount of AOX in the effluent exceeds the lesser of

(a) a monthly average of 1.0 kg of AOX/ADt of pulp produced in the bleach plant, or

(b) the maximum AOX discharge rate, expressed in kg/ADt, authorized by a permit issued under section 14 of the Act.

(2) Repealed. [B.C. Reg. 321/2004, s. 25 (f).]

(3) No permittee shall discharge effluent into the environment from an operation that produces pulp or paper unless the quality of the effluent is equal to or better than the quality requirement specified in Column 3 of Schedule 2.

(4) Subsection (3) does not apply to the pulp and paper mill operations at Port Alberni existing on July 6, 2004 or to the pulp mill operation at Port Alice existing on July 6, 2004.

(5) The pulp and paper mill operations at Port Alberni existing on July 6, 2004 shall not discharge effluent into the environment from those operations unless the quality of the effluent is equal to or better than the quality requirement in Column 4 of Schedule 2.

(6) The pulp mill operation at Port Alice existing on July 6, 2004 shall not discharge effluent into the environment from that operation unless the quality of the effluent is equal to or better than the quality requirement in Column 5 of Schedule 2.

(7) to (9) Repealed. [B.C. Reg. 188/2002, s. 1 (c).]

[am. B.C. Regs. 13/92, s. 2; 188/2002, s. 1; 321/2004, s. 25 (d) and (f).]

Sampling methods for compliance determination

3  (1) The compliance sampling method used to determine the effluent flow rate and temperature shall be as specified in writing by a director.

(2) The compliance sampling method used to provide an effluent sample for determination of the 96 h LC50 toxicity shall consist of a grab sample.

(3) The compliance sampling method used to provide effluent samples for determination of the 5 day biochemical oxygen demand (BOD5), the total suspended solids (TSS) and the AOX during phase I shall consist of collecting an effluent sample during a period of 24 hours by taking

(a) a continuous sample of the effluent being discharged from each effluent outfall,

(b) a composite of equal samples from each effluent outfall at least every 15 minutes, or

(c) a composite of samples from each effluent outfall at least every 15 minutes in an amount proportionate to the amount of the effluent.

(4) The compliance sampling method used to provide effluent samples for determination of BOD5, TSS and AOX during phase II shall be as specified in writing by the director.
