The Veil in Christianity • St. Paul in the New Testament made some very interesting statements about the veil: • "Now I want you to realize that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God. Every man who prays or prophesies with his head covered dishonours his head. And every woman who prays or prophesies with her head uncovered dishonours her head - it is just as though her head were shaved. If a woman does not cover her head, she should have her hair cut off; and if it is a disgrace for a woman to have her hair cut off or shaved off, she should cover her head. A man ought not to cover his head, since he is the image and glory of God; but the woman is the glory of man. For man did not come from woman, but woman from man; neither was man created for woman, but woman for man. For this reason, and because of the angels, the woman ought to have a sign of authority on her head" (I Corinthians 11:310).

State Definition for “Substantial Implementation” Region 3 Delaware Strategies substantially implemented – These strategies refer to “enforceable” protection measures or standards adopted at the local or state level that require protection of water quality or quantity in a source water areas ( wellhead and watershed). (Examples would be local ordinances with SWP regulations, County wide ordinances with SWP regulations, UST Secondary containment policy). Maryland Strategy developed and initially implemented means that a local planning team has been established agreed upon a strategy and implemented a portion of the strategy. Substantially implemented means that the most significant risks were or are being addressed by implementing a strategy. For example if a community purchased the recharge area for a well or spring source for protection then the strategy is substantially implemented, even if it was accomplished many years ago. Pennsylvania Virginia West Virginia Establishment of an approved local Source Water Protection Plan or the undertaking of relevant and sustainable actions/efforts that address priority risks as identified in the source water assessment. Waterworks has developed a watershed or wellhead protection plan. Plan does not have to be approved or certified by state but should include all elements of source water strategy such as: a. management team or advisory group that meets on a regular basis, b. identified potential contaminate source(s) [results of SWAPs], c. recommended action(s), and contingency planning [may be already stipulated in VA Waterworks Regulations] Any community public water supply system or a group of systems that has a protection plan in place and is addressing at least three of the top protection measures identified in its state supplied source water protection plan and/or locally defined protective measures approved by the state is considered substantial implemented. For systems serving 3,000 or fewer people, substantial implementation will be determined on a system by system basis.
