PEST MANAGEMENT POLICY Policies and Procedures Division: Environmental Services Unit: Grounds and Transport (Contracted Services) Policy / Procedure Topic: Pest Management Introduction Structural and landscape pests can pose hazards to people, property, and the environment. Pesticides which may be required to treat the problem are, by design, often toxic and pose a potential risk of their own. Policy To incorporate Integrated Pest Management (IPM)procedures in order to control structural and landscape pests in a safe, efficient and effective manner within the buildings and on the grounds of Dalhousie University. Note a) Dalhousie University contracts the services of a professional pest management company (herein referred to as "the contractor"), in order to fulfill its pest management obligations. b) All pesticides used by the contractor on Dalhousie University property are registered under the federal Pest Control Products Act and are identified by a Pest Control Product (PCP) number. c) All pesticide technicians employed by the contractor to perform work at Dalhousie University are certified applicators as specified and regulated under Section 84 of the Nova Scotia Environment Act. d) The Department of Facilities Management's commitment is to not use pesticides or herbicides in lawn and garden applications, other than in exceptional circumstances. Procedures 1) When a pest problem is encountered, the reporting departmental or faculty designate is to contact the Department of Facilities Management (Loc. #3302 or #3720) with the specifics (i.e., type of pest, if known; department name and location; contact person's name and local telephone number). The reporting department/faculty designate is not to contact the pest control contract company directly. 2) The Facilities Management designate will immediately contact the pest control contractor to report the specific problem and the details that have been provided in procedure #1. The contractor has been instructed to respond only when initially notified of a problem by the Facilities Management designate. 3) The contractor representative will call the department/faculty contact person to verify the problem and to arrange for a suitable time to service the affected area. 4) The contractor will visit the site at the earliest pre-arranged opportunity (but guarantees a site response within 24 hours). Every effort will be made to arrange for the site visit and any necessary treatment during business off-hours. 5) The contractor will notify the Facilities Management designate advising of any need for pesticide use, indicating the precise location and timing of the treatment. 6) A Facilities Management Environmental Services supervisor or designate will, in turn, notify Custodial Services personnel who may be assigned to the treatment area during business off-hours. Custodial Services personnel will abide by the re-entry information specified on the notice sign posted by the contractor (see procedure #7). 7) When ready to apply a pesticide treatment, the contractor will post a notice sign, in a prominent location at the application site. The notice sign will advise of the pesticide application and all relevant details (a sample of the posted notice sign is attached to this policy statement). 8) Once the pesticide application is complete, the contractor will note the details of the visit in the pest management log book, which is to be kept in the reception area (or other area designated by the departmental administrator) of each department/faculty. The details will include the date, reported problem, site observations, treatment (pesticide or otherwise), time of completion and recommended follow-up. The contractors applicator will include her/his signature indicating that the treatment visit is complete. A copy of the notice will be left with the Security Office for collection by an Environmental Services supervisor the following morning. 9) As appropriate, the contractor will notify the Facilities Management designate of any measures recommended to be taken by University staff in order to decrease the likelihood of a pest problem (for e.g.: the need to shampoo carpets in a given area in order to discourage a problem with fleas). Facilities Management will in turn inform the building manager or designate at the earliest opportunity. 10) Copies of all application notice signs will be filed in the Department of Facilities Management, the Security Office and the Safety Office. The contractor will supply an Annual Report of Pesticide Utilization at Dalhousie University. The report will include the number of applications and the name and amount of each pesticide used. The report will be filed with both the Department of Facilities Management and the Safety Office. Discussion Pests Pests are populations of living organisms (i.e., insects, rodents, bacteria and weeds) that interfere with the human purposes for an area. Strategies for managing pest populations will be guided by the species of pest and the threat they pose to people, property and the environment. Pests will be managed to: reduce any potential human health hazard or to protect against a significant threat to public safety prevent loss or damage to university structures or property prevent pests from spreading in the community or to plant and animal populations beyond the campus enhance the quality of life for university building occupants Integrated Pest Management (IPM) IPM procedures will determine when to control pests and whether to use mechanical, physical, chemical, cultural, or biological means. IPM practitioners depend on current, comprehensive information on the pest and its environment and the best pest control methods. Applying IPM principles discourages unacceptable levels of pest activity and damage by the most economical means and with the least possible hazard to people, property and the environment. The choice of whether or not to use a pesticide and, if so, which pesticide to use, will be based on a review of all other available options and a determination that these options alone are either not acceptable or feasible. Selected non-chemical pest management methods will be implemented appropriately. The full range of alternative pest control measures, including no action, will be considered. When it is determined that a pesticide must be used to meet important management goals, the least hazardous material will be chosen. The application of such pesticides is subject to regulation by federal and provincial legislation in the form of the Pest Control Products Act and the Nova Scotia Environment Act, respectively. http://www.dal.ca/dept/facilities/services/grounds/pest-management-policy.html

Horticultural vinegar is used as a weed killer when necessary or weeds are cut back regularly with a whipper snipper or pulled. Food gardens are grown organically with only organic fertilizers or natural soil additives such as manure or compost. Naturalized areas are minimally maintained. Plant selection is intended to mimic native ecosystems.

Dalhousie’s landscape design guidelines document outlines methods for tree protection during construction by requiring a tree barrier outside the tree dripline. This barrier prevents root damage and compaction during construction activity. When landscapes are disturbed, Dalhousie makes an effort to reuse all plant material before purchasing new plant material. As per the 2014 Natural Environment Plan, Dalhousie no longer plants species that are known to be invasive. Norway maple is the largest and most well known of these species and there is a program in place to phase this species out as they naturally decline. Native and adapted species will replace invasive and unsuitable plant species. These plants will be selected from a list of approved species that pose no risk to native ecosystems . The list of approved species is categorized according to their optimal planting conditions. This ensures that the best species are selected for the any given site.

As a policy, new development at Dalhousie cannot increase the flow of storm water from project sites. Halifax as a municipality does not allow new connections into the sewer/storm water system. Alternative methods (e.g., rain gardens, water cisterns, green roofs, permeable paving) must be explored to handle storm water. Retrofit projects shall use vegetated or the flow of storm water. The Mona Campbell Building on the Studley campus uses rainwater that would otherwise flow into catch basins to flush toilets. On going landscape upgrades on campus are increasingly incorporating rain gardens and permeable paving to get storm water into the ground quickly before it becomes a flooding issue.

On the Agricultural Campus, Dalhousie grounds staff compost garden and grass clippings as well as farm waste on site and re-use the compost as part of landscape management regimes. On the Halifax campuses, organic waste collected from landscape management activities is sent off-campus to a nearby composting facility. Plans are underway for an anaerobic digester at the Agricultural Campus.

Stormwater management actions are being taken with new projects such as adding water cisterns and green roofs in new buildings and permeable pavement. Two rain garden projects have been implemented to slow down water flow on university property.

Dalhousie Facilties Management staff stockpile sufficient salt for approaching storms on each of the three Halifax campuses to reduce the amount travel time by skid-steer loaders during each snow event. It is stored on impermeable surfaces as far as possible to limit contamination of soils and groundwater. Contractors are required to conform to Dalhousie’s anti idling policies and we attempt where possible to limit snow removal activities until the storm has passed so that clean-up is done once rather than repeatedly during a snow event. Salt application equipment is required to be calibrated for maximum efficiency. The Environmental Manager has Smart About Salt training. This information is shared with all Dalhousie snow removal staff. Contractors with Smart About Salt training are given preference in the RFP for snow removal services. We also try where possible to use alternatives to salt which are less corrosive but quite often the cost of these methods is prohibitive.
