This paper discusses ways of modifying the permit fees to reduce the costs for clients that carry out routine dredging or excavation and to set a maximum level for the fees. The first proposal is the introduction of an annual fee cap for disposal at sea permits for maintenance dredging and excavation operations. A fee cap would require amendments to the Ocean Dumping Permit Fee Regulations (Site Monitoring) under the (FAA) and be subject to the formal regulatory process. The second proposal involves a multi-year permit fee for maintenance dredging and excavation. This would require amendments to CEPA 1999.
This document summarizes both the results of public meetings and written responses received during public consultations conducted by EC in 2002-2003. The consultations focused on two issues. First was a three year review of the disposal site monitoring fees charged for disposal at sea permits for dredged material and excavated till. The second was EC's proposal for a method to determine the landward boundaries of application of the disposal at sea provisions of the CEPA, 1999.
This document outlines proposals for a process to be used in setting boundary lines between the sea and freshwater for the purposes of EC's Ocean Disposal Program. In particular this process will be considered as it applies to setting the boundary in major estuaries such as the Fraser River estuary in British Columbia, the Mackenzie River estuary in the North West Territories, and the Miramichi River estuary in New Brunswick. Consideration will also be given to how the process would work for areas of brackish water such as the Bras d'Or Lakes in Nova Scotia.
Public consultations occured in the winter 2003. A consultation report has been prepared.
In 1999, EC implemented a permit fee for the disposal at sea of dredged and excavated material at a rate of $470 per 1,000 cubic metres. The fee was estimated to be the fair market value of the right or privilege of permitting access to suitable disposal sites under the CEPA, 1999. A key commitment by EC to the regulated community was to review the fee three years after its implementation.
This paper was prepared for that review. It focuses on the issue of cost recovery through monitoring fees and presents an analysis of the fees paid, who paid them, how they have been spent, and an update on the costs of disposal site monitoring.

Application Form and Notice of Intent
To be completed using compatible word-processing software, printed out, and submitted with supporting documents to your nearest Program Office.
Alternatively, hard copies of the application form for a disposal at sea permit may be obtained from your nearest Disposal at Sea Regional Office.
The application must contain proof that a notice of the application was published in a newspaper of general circulation in the vicinity of the proposed loading and disposal activities to satisfy CEPA.
Examples of a permit and of an amendment as published in the Canada Gazette.
Annual Compendium of Monitoring Activities
This report is prepared each year as part of Canada's obligations under the London Convention and to the regulated community paying the monitoring fee. It presents summary results for each of the representative disposal sites monitored during the previous calendar year. The information presented varies with the issues of concern for a given site and the parameters examined. Monitoring activities may include:
- physical surveillance of the sea floor at the site such as a video camera survey or sonar survey by remote submersible,
- sampling sediments to examine their properties and analyzing for the presence of chemical contaminants,
- sampling sediments to examine their biological properties and conduct toxicity tests,
Details can be found in the Monitoring section.
Technical Guidance Documents and Monitoring Guidelines
National Guidelines for Monitoring Dredged and Excavated Material at Ocean Disposal Sites (EPSM-386)
The National Guidelines for Monitoring Dredged and Excavated Material at Ocean Disposal Sites provides advice to managers and professionals on developing and implementing monitoring projects at ocean disposal sites that receive dredged and excavated material. Issues discussed include:
- triggers to monitoring,
- developing monitoring plans,
- study design,
- data analysis, and
- biological assessment tools.
This document provides advice to managers and professionals on developing and implementing monitoring projects at ocean disposal sites that receive dredged and excavated material. Technical guidance is provided on:
- positioning equipment,
- sampling equipment,
- techniques for observing ocean disposal sites and defining their boundaries, and
- sediment transport models to predict short-term and long-term effects.
Guidance Document on the Collection and Preparation of Sediments for Physicochemical Characterization and Biological Testing (EPS 1/RM/29)
This guidance document examines the technical considerations of sample collection, preparation, handling and statistical design of sampling programs.
The disposal at sea program provides guidance on the design and completion of sampling projects to characterize the material proposed for disposal at sea. The following is a table of the minimum number of samples to be collected, based on the proposed volume of the project. It should be noted, however, that various factors can increase the required number of samples, such as proximity to sensitive or critical habitat, stratification of sediment layers at a dredge site, lack of information on potential sources of pollution or historical use of a site. Applicants are strongly encouraged, therefore, to consult with the nearest Disposal at sea regional office prior to finalizing or carrying out a sampling plan.
Sediment Quality Guidelines
Canadian sediment quality guidelines (SQG) for the protection of aquatic life are developed for individual chemicals for both freshwater and marine (including estuarine) sediments by the Water Quality Guidelines Task Group of the Canadian Council of Ministers of the Environment (CCME). EC's National Guidelines and Standards Office is the technical secretariat for the Task Group. These guidelines are numerical limits or narrative statements recommended to support and maintain aquatic life associated with bed sediments and are developed from the available scientific information on the biological effects of sediment-associated chemicals.
Pollution Gradient Study
The study was conducted by EC to assess tools used for permit assessment. Biological toxicity tests, chemistry, and benthic community structure were examined along a known pollution gradient in Sydney Harbour, Nova Scotia, Canada. Major contaminants were PAHs, PCBs, and heavy metals.
Biological Test Methods
EC has developed a series of biological test methods to measure various effects in sediments and porewater such as survival, growth and reproduction, and bioaccumulation. Test results are interpreted according to interim interpretation criteria. These tests are required in the permit application phase when chemical measurements indicate the Lower Action Levels of the National Action List are exceeded. As well, these methods are used in monitoring to confirm predictions of no significant biological impacts arising from disposal at sea.
