MISA Industrial MineralsSector
The Municipal/Industrial Strategy for Abatement (MISA) program is
Environment Ontario's program to reduce the discharge of toxic
contaminants to Ontario's waterways. Under the first phase of
MISA, dischargers were required to monitor and report on the
contaminants present in their effluent streams. This information
has subsequently been used to set legal discharge limits requiring
reductions in toxic discharges to the level attainable with the
best available pollution control technology which is economically
achievable. The ultimate goal of the MISA program is the virtual
elimination of persistent toxic contaminants from all discharges
into Ontario's waterways.
This document contains all the legal effluent discharge
requirements for Ontario's MISA Industrial Minerals Sector. These
requirements are specified in "Ontario Regulation (?)/93: Effluent
Monitoring and Effluent Limits - MISA Industrial Minerals Sector".
The regulation is issued under the Ontario Environmental Protection
Act (Section 136)
The "Ontario Regulation (?)/93: Effluent Monitoring and Effluent
Limits - MISA Industrial Minerals Sector" states the quality
discharge limits, toxicity testing, flow measurement, and reporting
requirements that each direct discharge industrial minerals plant

to implement pollution control strategies and install those capital
works necessary to meet the effluent limits.
Ontario Regulation (?)/93 states that sampling points must be
established at each industrial minerals plant site on every process
effluent stream, cooling water effluent stream, salt evaporator
plant effluent stream and emergency overflow effluent stream.
Routine monitoring requirements, designed to provide the Ministry
of Environment and Energy with assurance that the industrial
mineral plants are meeting the regulation requirements, are
tabulated in accompanying schedules.
This document consists of six chapters.
Chapter one of this document is introductory and presents the
environmental background to MISA and the main features of the
program. A description of the Effluent Monitoring Regulation for
the Industrial Minerals Sector is given and the generic effluent
limits regulation development process is explained.
Chapter two presents information about the Industrial Minerals
Sector. The sector consisted of approximately 116 plants. Plants
in the sector produce a variety of materials including portland
clinker, cement, lime, gypsum products, talc, graphite, clay brick,
roofing granules, magnesium metal, calcium metal, strontium metal.

talc, sand and gravel and crushed stone. The production processes,
water use, wastewater sources and wastewater treatment are
discussed in this chapter. With the exemption of pits and quarries
(sand, gravel, crushed stone, clay and shale) the sector currently
consists of 26 plants. The exempted plants will be regulated under
other Ministry control instruments.
Chapter three contains information about the effluent monitoring
data used in the development of the effluent limits. The chapter
includes a summary of the data collected under the one-year
regulated MISA effluent monitoring program. A summary of the MISA
effluent monitoring database for both regulated and non-regulated
plants is presented in Appendix III of this document. Data
validation, candidate parameter selection and QA/QC data assessment
are also discussed in this chapter.
Chapter four describes the assessment of available pollution
control technologies for the control of industrial minerals sector
effluent discharges and describes the identification of those
technologies considered to be the "best available". Chapter four
also examines the economic and financial implications of each of
the "best available" technology (BAT) train options, and presents
a summary of the likely impact of each BAT option on the sector.
Chapter five presents the effluent limits and describes the limit
development process. Existing control requirements are also
reviewed along effluent limits present in other jurisdictions.
Chapter six presents a summary of the key components of the
Effluent Monitoring and Effluent Limits Regulation for the
Industrial Minerals Sector. Compliance requirements and monitoring
frequencies are defined, as are other regulation requirements such
as toxicity testing criteria and flow measurement accuracy.
This Development Document represents the culmination of over six
years of effort on the part of the Provincial and Federal
governments, industry, and the public. The public review process
was a key component in the development of the Effluent Monitoring
and Effluent Limits Regulation for the Industrial Minerals Sector.

the Ministry who provide advice directly to the Minister on the
contents of the MISA regulations.
