The Department of Navy has completed its study on the groundwater aquifer on Tinian, according to the Marine Corps Forces Pacific, as Capitol Hill officials eagerly await a second wave of military studies on the impact of live-fire on the highly permeable limestone of Tinian.<\/p>\n
\u201cThe administration is hopeful the Department of Navy will heed the concerns that were addressed\u2014our comments, the EPA\u2019s (U.S. Environmental Protection Agency), and local agencies,\u201d said the administration of Gov. Ralph DLG Torres in a statement to Saipan Tribune last night.<\/p>\n
The highly permeable Marianas limestone\u2014which underlies most of the military project area on Tinian and \u201ccreates high susceptibility to contamination\u201d\u2014was not fully considered in the Navy\u2019s earlier studies, the U.S. Environmental Protection Agency said in October. The Navy noted then that the limestone was porous\u2014allowing water to readily flow through it\u2014and that rainfall percolates rapidly downward into such rock\u2014however\u2014no discussion of the solubility of munitions constituents were included, nor were \u201cany protections identified to prevent pollutants from infiltrating the soil and entering the aquifer,\u201d the EPA said then.<\/p>\n
\u201cThe Tinian Aquifer Study is complete and will be part of the Revised Draft [environmental impact statement],\u201d Craig Whelden, executive director of Marine Corps Forces Pacific, told Saipan Tribune in an email.<\/p>\n
Whelden also said his MARFORPAC team was in the CNMI all last week conducting meetings on various topics with CNMI officials. One of the meetings was on Tinian potable water. <\/p>\n
The military plans on drilling five new vertical wells on the land under military lease, from which to draw potable water.<\/p>\n
\u201cWith regards to water usage on Tinian, DOD is working with [the] CNMI to develop an alternative that is consistent with the lease,\u201d Whelden said.<\/p>\n
The forthcoming impact documents come after the military identified a need last October to undergo additional analysis of potential impacts to the ground water aquifer on Tinian; and coral on Tinian and Pagan, including related mitigation plans, among others.<\/p>\n
\u201cIt was because it wasn\u2019t in the EIS to begin with,\u201d Sen. Arnold Palacios (R-Saipan) said yesterday, referring to the EPA and CNMI Division of Environmental Quality-requested studies on impacts to Tinian groundwater. <\/p>\n
Palacios, a former Department of Lands and Natural Resources secretary, said there have been a lot of anecdotal evidence, or people telling of the \u201chundreds and hundreds of airplanes and military activities on Tinian\u201d and what these left on the island. <\/p>\n
\u201cSome of the chemicals are still there, are still found on the island of Tinian. Palacios said. \u201cDrums of chemicals are still found on pastures. It\u2019ll be very interesting for EPA to take a closer look at the water lens in the aquifer and project forward and what other impacts this activity will have.\u201d <\/p>\n
The military has laid out plans for four range complexes on Tinian inclusive of grenade, tank, pistol, and mortar activity, and have stated plans to drill five new vertical wells on Tinian from which to draw potable water.<\/p>\n
Palacios said the live-fire training could have potential long lasting impacts on a \u201cvery fundamental, almost basic resource\u201d\u2014water.<\/p>\n
\u201cThat is the most basic question that DEQ and EPA found lacking in the previous EIS study,\u201d he said. \u201cYou are talking about a substantial amount of live-fire and a substantial, protracted period of time\u2014we don\u2019t know. They can exercise it for however long, or\u2026stop\u201d while \u201cholding on to the lease,\u201d Palacios said.<\/p>\n","protected":false},"excerpt":{"rendered":"
