RECOMMENDATIONS: THAT The Metropolitan Toronto and Region Conservation Authority - 1. Protect the recreation resources of the Region, not only under the terms of the Ontario Water Resources Commission Act but also on the basjs of riparian rights; 2. Assist the Ontario Water Resources Commission in its task of super- vising sewage treatment programs for municipalities and of reconciling all demands for water uses in the Region through the adoption of the re- creation- pollution abatement plan for the Region as proposed in the staff report Recreation and Pollution Abatement in the Toronto Region, February, 1963; C -2 - 2 - 3. Recommend to the Ontario Water Resources Commission, Department of Municipal Affairs, the Metropolitan Toronto Planning Board and other Planning,Boards in the Region, that they consider this plan in formulating their policies on pollution abatement in the Region; 4. Request the Ontario Water Resources Commission to continue and intensify its research activities in the field of tertiary treatment of sewage including: (a) treatment of effluent in oxidation ponds (b) removal of suspended solids by sand filters (c) removal of dissolved salts such as nitrates and phosphates (d) removal of detergent materials such as A.B.S. 5. Where pollution from storm sewer discharges or storm overflows from combined systems occurs at upstream points, encourage treatment of these flows as far as economically reasonable; 6. Encourage conservation of sewage treatment plant residue from municipal and O.W.R.C. plants such as all forms of sludge to be used where appropriate as organic humus on farms and conservation areas as well as sub - marginal areas which can be reclaimed for reforestation, farming, etc. 7. Request the Province of Ontario to investigate any problems in pollution abatement posed by the general use of detergents, that is to investigate detergents as they may interfere with sewage treatment processes, excessively enrich receiving waters or indirectly create hazards to public health, and to take appropriate action to solve problems which may be revealed; $. Co- operate with upstream municipalities in facilitating tertiary treatment and disposal of sewage from present development, where such treatment is vital to the Authority's program, through the development of: (a) finishing ponds, to polish or eliminate final effluents, which can be used as well for public angling (b) reforested areas or areas of natural woodland for spray - irrigation disposal of secondary effluents 9. Request the Ontario Department of Municipal Affairs outside the Metropolitan Toronto Planning Area and the Metropolitan Toronto Planning Board inside the Planning Area to provide the Metropolitan Toronto and Region Conservation Authority with the opportunity of commenting on subdivision plans with respect to sewage disposal as it may affect schemes undertaken or to be carried out by the Authority. 10. Develop sewage treatment facilities in the Conservation Areas using: (a) wherever possible, within each heavily used Area, a decentralized system of several septic tank and tile field installations (b) where a high- capacity installation is required in any location within an Area, a conventional or total re- tention lagoon, or a package plant with irrigation, ponding or tile -bed disposal of the secondary effluent 11. Plan swimming areas in reservoirs in locations determined by flowage and water quality studies to be the best sites available; develop the areas to provide ample water volume in relation to the intensity of use; and provide a substrate of coarse sand or fine gravel to reduce roiling of the water in the swimming area; - 3 - 12. Co- operate with local Health Units in inspecting water and in studying and implementing on -site water treatment if quired; 13. Co- operate with local Health Units in locating points of domestic pollution so that Medical Officers of Health may require offending homeowners to correct polluting situations; 14. Assist municipalities and the Ontario Water Resources Commission in detecting the entry of trade wastes into water courses on its monthly checks on the river valleys; 15. Continue its program of streambank erosion control in upstream Conservation Authority lands and other valley lands in co- operation with local municipalities, expand streambank erosion control as an assistance program available to private landowners above reservoir sites and encourage farmers to protact streams and their banks from damage by cattle through the development of by -pass ponds and gravelled and fenced crossing and watering areas.

ADJOURNMENT: On Motion, the Meeting adjourned at 4:30 p.m. R.G. Henderson F.L. Lunn Chairman building, zoning, etc., of The Authority Re- co- operate by report- Carried Unanimously; Secretary - Treasurer C -1U SCHEDULE A Permissive Legislation Prior to April 26, 1963 section 20 of the Conserva- tion Authorities Act permitted an Authority to make regulations "prohibiting or regulating the construction of any building or structure, or the placing or dumping of fill of any kind, or on a pond or swamp or in any area below the high water mark of a lake, river, creek or stream." At the present time the Authority has, under the provisions of this section, regulations prohibiting and regu- lating the placing or dumping of fill below the high water mark of the rivers under its jurisdiction. These regulations have been in effect for approximately 30 months. As a result of experience gained in the administr- ation of these regulations it has become apparent there is a need for effective control over the placing or dumping of fill, not only below the high water mark of any river, but also within any portion of the valley systems under the Authority's jurisdiction, (i.e. anywhere below the upper edge of the valley). Accordingly, an amendment to the Conservation Authorities Act was requested. The requested amendments have been embodied in Bill 47 which received first reading February 11, 1963, second reading February 20, 1963, and third reading April 26, 1963. Under section 4 of Bill 47 legislation now permits an Authority to make regulations prohibiting the construction of any building or structure below the high water mark of a lake, river, creek, or stream as well as enlarging the control over filling to allow an Authority to make regulations prohibiting or regulating the placing or dumping of fill in any "defined part of the area over which the Authority has jurisdiction in which, in the opinion of the Authority, the control of flooding or pollution or the conservation of land may be affected by the placing or dumping of fill." In addition, the amendments in Bill 47 also provide permissive legislation allowing a magistrate to order the removal of fill and any buildings in addition to any other penalties provided by law, in the case of a conviction. This court authority provides the real 'teeth' for the said regulations. Present Status of MTRCA Fill Regulations At the present time the Authority's Fill Regulations now in effect, are still a. initially constituted in 1960 under the original permissive legislation. These regulations provide for control of fill below the high water mark of rivers under MTRCA control. New Regulations Since the passing of Bill 47 the staff, the Authority Solicitor, and the Registrar of Regulations for the Province, have been engaged in the preparation of new regulations in order to take full advantage of the control now offered by the amendments embodied in Bill 47. After many revisions, the following set of regulations was crystalized and agreed upon. Continued -2- REGULATION MUL UNDER THL CONSERVATION AUTHORITIES ACT FILL AND CONSTRUCTION C -11 1.
