A House provision to undermine basic environmental safeguards and squelch citizen involvement was included in the three-month extension intended for conference with Senate. House leaders last week passed their three-month transportation bill extension to serve as a “shell” to get them to the negotiating table with the Senate. But in order to keep more conservative members happy, they included three anti-environment provisions, two of which — the Keystone XL pipeline and de-regulation of coal ash — unrelated to transportation.
