NEWFOUNDLAND AND LABRADOR REGULATION 65/03

Short title

1. These regulations may be cited as the Environmental Control Water and Sewage Regulations, 2003.

Definitions

2. In these regulations

(a) "Act" means the Water Resources Act;

(b) "composite sample" means a quantity of undiluted effluent collected continually at an equal rate or at a rate proportionate to flow over a designated sampling period; and

Sewage discharge compliance

3. A person discharging sewage and other materials into a body of water, public sewer or sewer leading to a public sewer shall comply with the standards, conditions and provisions prescribed in these regulations for the constituents, contents or description of the sewage or other discharged materials.

Discharge of materials

4. (1) A person shall not discharge sewage or other effluent into a public sewer or a sewer leading to a public sewer containing materials which would obstruct or impede the flow of sewage within the public sewer or impair or interfere with the public sewer or sewage works of that public sewer.

(2) The materials referred to in subsection (1) include oil or by‑products of oil, flammable, explosive, toxic, poisonous or corrosive liquids, solids or gases, fats, congealing materials and other substances in quantity which interfere with the free flow within the public sewer.

Specified discharge prohibition

5. A person shall not discharge into a public sewer or sewer leading to a public sewer, sewage or effluent

(a) containing a constituent specified in Column 1 of Schedule B having a content in milligrams per litre, parts per million, in excess of the maximum specified in Column 2 of that Schedule;

(b) having a temperature in excess of 65° Celsius; or

Specified discharge prohibition

6. A person shall not discharge into a body of water sewage or effluent

(a) containing a constituent specified in Column 1 of Schedule A having a content in milligrams per litre in excess of the maximum specified in Column 2 of that Schedule;

(b) having a temperature in excess of 32° Celsius;

(d) a radio‑active substance having a gross beta activity before discharge of more than 37 Bq per litre with the exception of

(i) radium 226 which shall not exceed 0.37 Bq litre, and

(ii) strontium 90 which shall not exceed 0.37 Bq per litre.

Discharge not construed by regulations

7. Nothing in these regulations shall be construed to permit the discharge of a pollutant into a body of water.

Analysis procedures

8. Notwithstanding sections 5, 6 and 7, all analytical work in relation to effluent samples and receiving water samples is to be carried out using analytical procedures acceptable to the Assistant Deputy Minister of Environment of the Department of Environment of the Government of Newfoundland and Labrador.

Sampling

9. (1) A person taking effluent samples or receiving water samples shall take them as composite samples or as grab samples.

(2) In the case of composite sampling, all levels are required to be within the appropriate values as established in sections 5 and 6 and Schedules A and B.

(3) In the case of grab sampling, 90% of all levels taken in one month shall be within the appropriate values as established in sections 5 and 6 and Schedules A and B.

Monitoring

10. The minister may, for specific purposes and time periods as he or she may determine, require that a water user or discharger of sewage monitor its effluent for the constituents in sections 4 and 5 and Schedules A and B report the effluent quality.

Repeal

11. The Environmental Control Water and Sewage Regulations, Consolidated Newfoundland and Labrador Regulation 1078/96, are repealed.

NOTES:

(1) If water is being abstracted from a water course, used, treated and subsequently returned to the same water course, these solids data mean that the effluent should not contain more than 1000 or 30 milligrams per litre more than was in the water originally abstracted.

(2) 1 bequerel (bq) ‑ 27.03 pico‑curies. Bequerel is the SI unit for the measure of radioactivity.

(3) All metal results should be the total of the particulate and the dissolved fractions of that metal and the maximum content is the amount in excess of the background level as determined upstream of the discharge.
