HALT Penneast to FERC
R. Steven Richardson 1776 K STREET NW September 12, 2016 202.719.7489 WASHINGTON, DC 20006 [email protected] PHONE 202.719.7000 www.wileyrein.com Kimberly Bose Secretary Federal Energy Regulatory Commission 888 First Street, NE Washington, D.C. 20426 Re: PennEast Pipeline Project’s Impacts on Drinking Water FERC Docket No. CP15-558 Dear Ms. Bose: I am writing on behalf of Homeowners Against Land Taking-PennEast (“HALT”). HALT represents over two hundred impacted landowners in towns along PennEast’s proposed pipeline route. HALT intervened in this proceeding on February 3, 2016. Its members are concerned that the Draft Environmental Impact Statement (DEIS) does not accurately assess the risk of arsenic contamination from the proposed pipeline in groundwater, including landowners’ drinking water. It is well known that arsenic concentrations in water can lead to short-term and long-term health effects, including increased cancer risks, cardiovascular effects, numbness and burning sensations, nausea, and other health risks. HALT is alarmed that FERC has failed to consider these impacts on public health from the construction and operation of the pipeline, despite clear and uncontroverted evidence that the abundant concentrations of arsenic in the areas of New Jersey along the proposed pipeline likely will be mobilized by both construction and operation of PennEast’s pipeline. Although Section 4.1.5.5 of the DEIS provides superficial discussion of the risk that the pipeline would cause arsenic contamination of local water sources, the DEIS’s analysis of this risk is deeply flawed for multiple reasons. First, the DEIS relies on a defective study of arsenic contamination provided by PennEast (the Serfes Report).1 FERC must withdraw the DEIS and base its conclusions on an accurate study. -
Paleomagnetism and U-Pb Geochronology of the Late Cretaceous Chisulryoung Volcanic Formation, Korea
Jeong et al. Earth, Planets and Space (2015) 67:66 DOI 10.1186/s40623-015-0242-y FULL PAPER Open Access Paleomagnetism and U-Pb geochronology of the late Cretaceous Chisulryoung Volcanic Formation, Korea: tectonic evolution of the Korean Peninsula Doohee Jeong1, Yongjae Yu1*, Seong-Jae Doh2, Dongwoo Suk3 and Jeongmin Kim4 Abstract Late Cretaceous Chisulryoung Volcanic Formation (CVF) in southeastern Korea contains four ash-flow ignimbrite units (A1, A2, A3, and A4) and three intervening volcano-sedimentary layers (S1, S2, and S3). Reliable U-Pb ages obtained for zircons from the base and top of the CVF were 72.8 ± 1.7 Ma and 67.7 ± 2.1 Ma, respectively. Paleomagnetic analysis on pyroclastic units yielded mean magnetic directions and virtual geomagnetic poles (VGPs) as D/I = 19.1°/49.2° (α95 =4.2°,k = 76.5) and VGP = 73.1°N/232.1°E (A95 =3.7°,N =3)forA1,D/I = 24.9°/52.9° (α95 =5.9°,k =61.7)and VGP = 69.4°N/217.3°E (A95 =5.6°,N=11) for A3, and D/I = 10.9°/50.1° (α95 =5.6°,k = 38.6) and VGP = 79.8°N/ 242.4°E (A95 =5.0°,N = 18) for A4. Our best estimates of the paleopoles for A1, A3, and A4 are in remarkable agreement with the reference apparent polar wander path of China in late Cretaceous to early Paleogene, confirming that Korea has been rigidly attached to China (by implication to Eurasia) at least since the Cretaceous. The compiled paleomagnetic data of the Korean Peninsula suggest that the mode of clockwise rotations weakened since the mid-Jurassic. -

Hence the fundamental entity is the magnetic dipole arising from an electric current I circulating in a conducting loop, such as a wire, with area A . The field is described as resulting from a magnetic dipole characterized by a dipole moment m Magnetic dipoles can arise from electric currents - which are moving electric charges - on scales ranging from wire loops to the hot fluid moving in the core that generates the earth’s magnetic field. They also arise at the atomic level, where they are intrinsic properties of charged particles like protons and electrons. As a result, rocks can be magnetized, much like familiar bar magnets. Although the magnetism of a bar magnet arises from the electrons within it, it can be viewed as a magnetic dipole, with north and south magnetic poles at opposite ends. 4 2-3 MAGNETIC FIELD 5 We visualize the magnetic field of a dipole in terms of magnetic field lines pointing outward from the north pole of a bar magnet and in toward the south. The lines point in the direction another bar magnet, such as a compass needle, would point. At any point, the north pole of the compass needle would point along the DIPOLE field line, toward the south pole MAGNETIC of the bar magnet. -
