APPENDIX K 

DRAFT WETLAND REMEDIAL REVEGETATION PLAN 
Kern River Gas Transmission Company

Apex Expansion Project

DRAFT Wetland Remedial Revegetation Plan

Kern River will, in general, follow the procedures specified in the Reclamation Plan

(Volume 4B – Appendix 7D), and based on the criteria or goals as referenced in Section VI.D(4) 

of Kern River’s Wetland and Waterbody Construction and Mitigation Procedures (Volume 4B –

Appendix 2B) for wetland revegetation. This Wetland Remedial Revegetation Plan outlines 

methods Kern River will utilize in the unlikely event that restoration of wetlands does not meet 

the stated goals. The stated goals are that wetland revegetation will be considered successful 

when the restored right-of-way (ROW) and associated temporary work space reaches 80 

percent of the type, density, and distribution of vegetation, when compared to an adjacent 

wetland area, after three years (with the exception of large rooted trees which will not be 

allowed to grow back within 10 feet of the pipeline centerline. Kern River notes that based upon 

qualitative and quantitative revegetation monitoring following the Kern River 2003 Expansion, 

remedial revegetation efforts are not anticipated within the wetlands to be traversed by the 

Project. Data from the 2003 Expansion Project demonstrated that, within three years of 

construction, wetland success criteria had been met or exceeded in all wetlands in similar 

areas, including wetlands in Summit, Morgan and Salt Lake counties, Utah.

Remedial Revegetation Measures

In the event that post-construction restoration of wetland habitats does not meet the 

stated success criteria by the third year post-reclamation, Kern River will conduct a site-specific 

assessment to determine the basis for the lack of plant performance in not meeting the stated 

goals. Based on this assessment, appropriate remedial measures will be implemented. 

Remedial restoration measures must address the requests and requirements of 

landowners or the appropriate land management agency, and will be based upon assessed field 

conditions at that time. While Kern River cannot completely control the actions of the 

landowners or other third parties who may use Kern River’s ROW or areas of temporary work 

space following construction and reclamation activities, Kern River will implement the necessary

steps required to remediate those areas where site-specific restoration monitoring surveys have 

determined that failure to meet stated success criteria is a direct result of inadequate 

revegetation following Kern River’s construction and initial reclamation activities. 

A combination of the following measures may be utilized where wetland revegetation 

does not meet the stated success criteria as follows:

Plant Protection Measures

If site-specific field surveys determine that livestock or wildlife grazing impacts have 

negatively affected the reestablishment of wetland communities, Kern River will implement plant 

protection measures such as exclusion fencing, to the extent possible, upon consultation with 

the landowner or land managing agency. In addition, based upon field conditions at that time, 

exclusion fencing may be utilized in combination with soil decompaction, direct seeding and/or 

noxious weed control as further provided below. 
Soil Decompaction

If site-specific field surveys determine that post-construction wetland restoration does 

not meet stated goals in wetlands due to incomplete decompaction as part of restoration 

activities, Kern River will decompact the soils to a minimum depth of 12 inches using a standard 

sub-soiler/heavy duty chisel plow or similar type of decompaction equipment, and supplement 

with additional direct seeding as necessary. Decompaction will only be proposed if wetland 

conditions can support the necessary equipment without excessive rutting of the soils.

Direct seeding

If site-specific field surveys determine that revegetation does not meet the stated 

success criteria of type, density and distribution, when compared to an adjacent area, Kern 

River will assess the need to reseed the affected area with an approved seed mixture as 

specified in Section 6 of the Reclamation Plan (Seed Mixtures UT-3, wet meadow communities; 

or UT-3A, saline/alkaline communities). Kern River will also coordinate with the local soil 

conservation district and the landowner or land management agency to assess an alternate sitespecific seed mix specifically developed for the existing offsite conditions.

Noxious Weed Control

If site-specific field surveys determine that restoration of Project impacts does not meet 

stated goals due to an infestation of federal, state or locally listed noxious weeds, Kern River will 

implement specific methods outlined in the Noxious Weed Control Plan, included as Appendix 

7C in Volume 4B, and overseed the affected area with an approved seed mixture as specified in 

Section 6 of the Reclamation Plan (Seed Mixtures UT-3, wet meadow communities; or UT-3A, 

saline/alkaline communities).
