class=\"has-inline-color has-theme-palette-2-color\">Types of studies included in EEMS<\/mark><\/strong><\/p>\n\n\n\n<p>EEMS comprise several complementary components, which differ depending on the applicable regulation:<\/p>\n\n\n\n<p><strong>1) Sublethal toxicity tests<\/strong><\/p>\n\n\n\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-8cf370e7

B).<\/p>\n\n\n\n<p>\u2022 Objective: to evaluate the survival, growth, and reproduction of sensitive aquatic organisms (algae, daphnia, fish) exposed to effluents.<\/p>\n<\/div>\n\n\n\n<p><strong>2)

habitat, and their use<\/strong> \u2014their terms differ in several key respects.<\/p>\n\n\n\n<p><strong>1. Mandatory framework<\/strong><\/p>\n\n\n\n<p><strong>Mining (REMMMD)<\/strong> ESEE are <strong>automatic and systematic<\/strong> for any site that rejects more than <strong>50 m\u00b3\/day of effluent<\/strong> or who deposits a harmful substance into water frequented by fish.<\/p>\n\n\n\n<p><strong>Pulp and paper (REFPP)<\/strong> ESEE are <strong>automatic<\/strong> and systematic for any site that discharges more than 50 m\u00b3\/day of effluent or deposits a deleterious substance in water frequented by fish.<\/p>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<p><strong>2.<\/strong> <strong>2. Parameters monitored<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mining (REMMMD)<\/strong> Monitoring focuses primarily on <strong>contaminants resulting from ore processing<\/strong> (metals, suspended solids). Concentrations of <strong>mercury<\/strong> and of <strong>selenium<\/strong> in effluent determine whether fish tissue analyses should be conducted.<\/li>\n\n\n\n<li><strong>Pulp and paper (REFPP)<\/strong> the focus is on <strong>rganic compounds<\/strong> (BOD, AOX, bleaching by-products). Concentrations of <strong>chlorinated dioxins<\/strong> and of <strong>furans<\/strong> are used as indicators to decide whether fish tissue analyses are necessary (Appendix V).<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Regulatory calendar<\/strong><\/p>\n\n\n\n<p>The regulatory calendars of the REMMMD and the REFPP have many similarities, particularly in the following areas:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Three-year cycle duration<\/li>\n\n\n\n<li>Possibility of reducing the frequency of follow-ups for certain studies if two consecutive cycles have shown no effect<\/li>\n\n\n\n<li>Minimum period of 6 months between submission of the study plan and completion of the biological monitoring sampling campaign<\/li>\n\n\n\n<li>Submission of the interpretation report for the first cycle at a site no later than 3 years after becoming subject to the program<\/li>\n<\/ul>\n\n\n\n<p>The following characteristics differ between the REMMMD and the REFPP:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Period<\/strong><\/td><td><strong>Mining (REMMMD)<\/strong><\/td><td><strong>Pulp and paper (REFPP)<\/strong><\/td><\/tr><tr><td><strong>First cycle schedule following subjection<\/strong><\/td><td>The first study plan must be submitted <strong>within 12 months of subjection.<\/strong>.<\/td><td>No additional requirements related to the first cycle study plan.<\/td><\/tr><tr><td><strong>Closure<\/strong><\/td><td>In the event of <strong>effluent closure<\/strong>, a <strong>final study<\/strong> is required, with a plan to be submitted within 6 months of notification and a final report within 3 years.<\/td><td>In the event of a<strong>production shutdown for at least eight consecutive months without resumption<\/strong> of production, biological monitoring studies are put on <strong>hold<\/strong>.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>These differences directly influence <strong>planning<\/strong>the <strong>resource management<\/strong> and the <strong>compliance strategy<\/strong>.
