Point To Non-point Phosphorus Trading In The
South Nation River Watershed
Author(s)
D. O’Grady
Abstract
The South Nation River watershed has a regulated water quality trading
program. By law, waste water dischargers must discharge 0 kg of phosphorus
(P) loadings into receiving waters. New wastewater systems are now choosing
trading instead of traditional P removal technology. These point source
dischargers are buying P credits from rural landowners, primarily farmers.
These credits are generated by constructing non-point source pollution control
measures, and calculating the kg of P removed by each measure. South Nation
Conservation, a community based watershed organization, is the broker for these
P credits. The program is run by a multi-stakeholder committee, and all project
field visits are done by farmers and not paid professionals.
Keywords: water quality trading, phosphorus trading, water credit trading,
watershed trading.
1 Introduction
South Nation Conservation (SNC) is a community based watershed organization
set up to manage the natural resources of the South Nation River watershed.
Over the last several years, SNC paid over $1 million in grants to rural
landowners for various non-point source pollution control projects.
The South Nation River watershed is located southeast of Ottawa, Ontario
Canada. The 4,000 sq. km. watershed has a population of 125,000, and is mixed
farming with dairy, cash crop corn and soybeans predominant.
The South Nation River has peak flows of over 1,000 cu. m./s. in the spring
freshet, and less than 20 cu. m./s. during summer low flows. There are currently
16 wastewater lagoons in the watershed (14 municipal, 2 industrial). Provincial
guidelines allow the lagoons to discharge their effluent at peak flows, primarily
in the spring, for dilution of effluent to meet Provincial water quality guidelines.
Keywords
water quality trading, phosphorus trading, water credit trading,
watershed trading.
