New or rewritten text appears in blue in the Revised EA. Chapter 1 – Purpose and Need Page 15 A Cost Implementation issue was added to the list of issues not analyzed in detail. Page 16 Information was added to the Public Comment Period section. Page 17 Information was added to the Tribes and Endangered Species Act subsections of the Consultation section. Page 22 A footnote was added to the Cascade-Siskiyou National Monument Resource Management Plan section that clarifies that although there have been recent recommendations to reduce the size of the Monument, there are no BLM planning actions proposed or underway. Chapter 2 – Integrated Invasive Plant Management and the Alternatives Page 27 It was noted that NISIMS will be accessible to the public in 2018. Page 36 A footnote was added clarifying when blackberry would be treated. Pages 36, 41 It was clarified that Treatment Acres are “Gross Treatment Acres,” and a Figure (Figure 2-1) has been added to clarify the difference between gross and net acres. This updated headers in Tables 2-1 (28-35) and 2-3 (pages 39-40), as well as the Treatment Key (Tables 2-12 and 2-13, pages 74- 76). Page 43 Lythrum tribracteatum was added to Category IV, New Invaders. Page 45 Information was added to the Planning section that states that the BLM maintains a list of non- native species not known to be invasive in most circumstances. That list has been removed from Table 2-3 (pages 37-40) and moved into Table D-3 (342-344). Page 46 Information was added about the Determination of NEPA Adequacy that would accompany Annual Treatment Plans. Pages 47-51 An Anticipated Treatment Window column was added to the Annual Treatment Plan. Updates were made to two projects. Page 56 It was noted that the ODA is currently evaluating additional biological control agents for several invasive species. Page 58 Figure 2-4 was added, showing ground herbicide treatments with a backpack sprayer. Page 61 Vastlan was added to the list of representative trade names for triclopyr in Table 2-8, Herbicide Information. It was also clarified that triclopyr treats blackberry. Additional information about the fluazifop-P-butyl label was included in a footnote. 3 Integrated Invasive Plant Management for the Medford District Revised Environmental Assessment Changes to the EA Pages 71 Additional Project Design Features were added to the Proposed Action. Page 72 Clarification about where known locations of aquatic invasive plants were located was added to Alternative 3 and additional information was added to explain how flowing streams would be treated. Page 75 Imazapyr was added to Treatment Group D11 and triclopyr was added to Treatment Group D8. Page 75-76 It was noted that treatment methods are based on best current science and the experience of invasive plant control professionals and that as new information becomes available about effective (or ineffective) treatment options for species or species groups, modifications to the Treatment Key may be considered as part of the Annual Treatment Plan. Pages 81, 83-84 Additional detail was added to some of the alternatives in the Alternatives Considered but Eliminated from Detailed Study section. Page 89 The Pacific Connector Gas Pipeline was added to Table 2-16, Reasonably Foreseeable Actions. Chapter 3 – Affected Environment and Environmental Consequences Page 152 Additional information was added about the effects of glyphosate to honeybees in agricultural settings. Page 155 A Project Design Feature was added to Wildlife Issue 1. The Project Design Feature was also added to Appendix A (page 250). Page 165 A Project Design Feature was added to Human Health Issue 1, and clarification about the Project Design Feature was added in a footnote. The Project Design Feature was also added to Appendix A (page 250) and referenced in Recreation Issue 1 (page 216). Page 164 Clopyralid was added to Table 3-14, Effects of Herbicides to Human Health. Page 167 Additional information about correlations between work conditions and disease was added to Human Health Issue 2. Pages 167-168 Corrections were made to the Alternative 3 treatment acres column on Table 3-15, Human Health Herbicide Risk Summary, Workers. Pages 177-178 A line stating that herbicides would never be directly applied to soils was removed from Soil Issues 2 and 3. Page 182 Errors in Table 3-21, Pesticide Movement Rating, were fixed, the header was clarified, and a footnote on Table 3-35, Effects of Herbicides available under the Proposed Action and Alternative 3 (Water), (page 188) was updated to include information about pesticide movement through soils. Page 188 The triclopyr information in Table 3-25, Effects of Herbicides available under the Proposed Action and Alternative 3 (Water), was updated to include information about both TEA and BEE formulations. Page 189 Clarification that an effect would be short-term was added to the Water Issue 1 Cumulative Effects section. 4 Integrated Invasive Plant Management for the Medford District Revised Environmental Assessment Changes to the EA Page 202 Edits were made to Traditional and Cultural Uses Issue 1 to clarify that areas treated with herbicides would have posted signs. Pages 211-213 A Cost Implementation Issue (not analyzed in detail) was added to the analysis. Appendices Pages 297-300 Edits were made where various Biological Assessments were quoted in the Protections Measures for Federally Listed Species section to clarify that the text came from the Biological Assessments. Pages 342-344 Table D-3, Summary of Other Non-Native Plant Species that May Be Invasive in Some Circumstances, was added and includes species removed from Table 2-3 (pages 37-41). These species were also removed from Table D-2, Species and Treatment Groups (pages 337-342). Other Changes Invasive plants were recharacterized as “infestations” rather than “populations.” Additions or corrections were made to References (pages 234-248) and List of Preparers (page 221). Minor edits were also made throughout the document to fix typos or sentence structure. 5 Integrated Invasive Plant Management for the Medford District Revised Environmental Assessment Table of Contents Table of Contents Chapter 1 – Purpose and Need ............................................................................................................................ 10 The Need ....................................................................................................................................................................
