Terry, the entire facility has not been disturbed. Only most of it. Id say
approx 70%. The other 30% has been impacted but not tot the point of disturbing all the vegetation, just foot and vehicle traffic. I dont have problem with saying the above, but keep in mind, the facility has been there and just because the trees havent been disturbed, doesnt mean that the understory beneath the trees has been pristine. It has always been Transwetern's policy to maintain an environmetnal presence at all of its locations, especially at sites where there is some aesthetic value (scenery wildlife etc). I dont have a problem with including resource reports 3 and 7 for vegetation and soils. I have received a verbal from the US Fish and Wildlife and they agreed with the intent in my letter to them that pipline activites at each location tend to preclude any impacts to sensitive or critical habitats. In addition, the adjacent lands are of the same habitat types as that which are contained within the facility and therefore, would not be an issue of habitat loss. There are not any old TW hands around to positively verify that the site was cleanred and there has been natural encroachment of the trees into the area, I seriously doubt it. Again, TW tried to mantain a postive presence at each site, but did utilize the sites for their intended purpose. In Arizona, we do not have a blanket approval for discharges of hydrostatic testwater. We do however plan to use new pipe and water supplied either from the closest City (ie Flagstaff for station 2 construction) or from a drinking well source. In any event, we will test the water prior to discharge and ensure that the discharge will stay on the facility property to soak into the ground. I cant imagine that there will be large volumes of hydro water as we dont plan on installing a large amount of new pipe. If we need to discuss the above, give me a call "Hackett, Terry" <THackett@ENSR.com< on 03/09/2001 02:18:52 PM To: "'Larry.Campbell@enron.com'" <Larry.Campbell@enron.com< cc: "'Donna.Martens@enron.com'" <Donna.Martens@enron.com< Subject: Station 2 Concerns Larry, I gave the tree issue at Station 2 some thought and I have a couple of concerns regarding the environmental report. The report is being written, based on the fact that all construction will occur within the station yard and on previously disturbed ground. If we impact areas (even within existing facilities) that were not previously disturbed we are required to include environmental data about those areas. So the first question is whether the entire station yard has been "previously disturbed". To help determine this, I downloaded a USGS aerial (1996) of the station from the internet and the trees occurring within the station yard look to be the same age/size as those surrounding the station. This would indicate that the areas within the station covered with trees have not been "previously disturbed". A copy of the aerial is attached. However, it is conceivable that the site was cleared prior to initial construction and the trees simply grew back. Unfortunately, I don't have that information and don't know if you do either. And let me point out that my concern is not whether Transwestern will receive approval to construct, but the amount of information supplied in the report. I want to feel comfortable that we are supplying the required information to FERC. For this project, that would primarily include a description of the existing vegetation and soils (resource report 3 and 7). All we would really need is a brief description of the existing vegetation and soils, and how much will be permanently impacted, etc. However, we did not budget any time to obtain this information, nor did we anticipate the need for site visits. My hope is that we can find an answer to whether the site was previously disturbed or not. If not, I hope to come up with some verbiage that everyone is comfortable with to satisfy the FERC requirements. Otherwise, we will have to obtain the necessary information, and that's beyond our initial scope. If you have had any biological reports done for the area on other projects, that may provide enough information. Again, it only needs to be brief. Also, we need to verify for the other 3 stations that we are constructing in previously disturbed areas. Lastly, Arnold has indicated that the hydro-test water will come from existing water source at each station and that it will be discharged under Transwestern's blanket permit. Please verify...and I think we should provide a copy of the blanket permit with the filing. After you have had a chance to think about this, please call and we can discuss.
