Ahyayha Smith Creek Trout Restoration Nitrogen Reduction Certificate Standards
1. The Project as described in the Certificate is (was) implemented.
Public Policy Virginia dba The Center for Natural Capital, a 501 c-3 entity managing the Ahyayha Project, assures that the project described on the Ahyayha website has or will be completed.
2. Each certificate is unique.
Each certificate provided to a project Supporter is unique and cannot be duplicated to ensure against double counting. Each certificate has a tracking number kept in a private registry.
3. Peer reviewed science was used to estimate sequestration.
Scientific literature was reviewed to find the most relevant information to estimate nitrogen sequestration likely to occur as a result of the project. Methodology used to calculate sequestration is described in Appendix I.
4. The project is inspected (verified).
Ahyayha staff will travel to the project to verify completion and ongoing continuation of project functionality within the stated project timeframe. This information will be posted to the Ahyayha project website.
5. Certificate Warranty
Except for the express standards set forth above, Public Policy Virginia dba The Center for Natural Capital makes no other warranties relating to the certificates express or implied as to any matter whatsoever, including without limitation the condition of the Certificates.
Information developed and cited in the papers “Sediment and Nutrient Loads from Stream Corridor Erosion along Breached Millponds” (Merritts et. al., 2010) and “Recommendations of the Expert Panel to Define Removal Rates for Individual Stream Restoration Projects” (Schueler and Stack, 2013) were used to estimate nitrogen removal for the Smith Creek Streambank Restoration Project.
Based upon this information, it was estimated that the restoration project reduces 1.7 lbs nitrogen per linear foot per year. Since it was also assumed that the likelihood of background rate of conversion is none, this removal estimate was credited for one year only. Based on an estimated cost of $8400 for 50 linear feet of restoration, the 2013 cost per pound is estimated to be $99.26.
