  • Tennessee Erosion & Sediment Control Handbook
    TENNESSEE EROSION & SEDIMENT CONTROL HANDBOOK A Stormwater Planning and Design Manual for Construction Activities Fourth Edition AUGUST 2012 Acknowledgements This handbook has been prepared by the Division of Water Resources, (formerly the Division of Water Pollution Control), of the Tennessee Department of Environment and Conservation (TDEC). Many resources were consulted during the development of this handbook, and when possible, permission has been granted to reproduce the information. Any omission is unintentional, and should be brought to the attention of the Division. We are very grateful to the following agencies and organizations for their direct and indirect contributions to the development of this handbook: TDEC Environmental Field Office staff Tennessee Division of Natural Heritage University of Tennessee, Tennessee Water Resources Research Center University of Tennessee, Department of Biosystems Engineering and Soil Science Civil and Environmental Consultants, Inc. North Carolina Department of Environment and Natural Resources Virginia Department of Conservation and Recreation Georgia Department of Natural Resources California Stormwater Quality Association ~ ii ~ Preface Disturbed soil, if not managed properly, can be washed off-site during storms. Unless proper erosion prevention and sediment control Best Management Practices (BMP’s) are used for construction activities, silt transport to a local waterbody is likely. Excessive silt causes adverse impacts due to biological alterations, reduced passage in rivers and streams, higher drinking water treatment costs for removing the sediment, and the alteration of water’s physical/chemical properties, resulting in degradation of its quality. This degradation process is known as “siltation”. Silt is one of the most frequently cited pollutants in Tennessee waterways. The division has experimented with multiple ways to determine if a stream, river, or reservoir is impaired due to silt.

  • Definitions of "Soil" and "Mineral"
    OFFICE OF SURFACE MINING RECLAMATION AND ENFORCEMENT U.S. Department of the Interior COALEX STATE COMPARISON REPORT - 113 June 12, 1989 William O. Roller Division of Mineral Mining P.O. Box 4499 Lynchburg, Virginia 24502 TOPIC: DEFINITIONS OF SOIL AND MINERAL INQUIRY: A permit is required for an operator to extract minerals from the earth. Is clay which is excavated from a borrow pit and used for fill dirt in construction considered a "mineral", requiring a permit, or "dirt" which would not require a permit, for removal? Locate state laws which define "minerals", "soil", or "dirt". SEARCH RESULTS: Research was conducted using the state code files on LEXIS. At the time the research was performed, codes for 32 states were available. Summaries of the identified state code sections are listed in table format below. Excerpts from the identified sections and the list of states searched on LEXIS are included as appendices. Research was also conducted using the state and federal case law files on LEXIS. The decisions identified as a result of the research and the topics they discuss are listed below. Copies of the decisions are enclosed as appendices. STATUTES AND CODES FINDINGS 1. Many mining- or natural resource-related sections include "clay" in the definition of "mineral". In some cases, the definition of mineral is qualified by the phrase "in this Act". 2. Many mining and natural resource sections use the words "soil" and "earth" almost interchangeably; the word "dirt" is virtually never used. 3. When used in state codes, the word "dirt" usually means "foreign substance", "filth", or "stain" and appears in codes dealing with food, agricultural products and dry cleaning.

Is topsoil mixing permitted in the Mining (M) zone? Background This question was reviewed by the RRC on May 30, 1997. Topsoil screening or mixing includes importing sand, sawdust, finish compost, peat, and dirt and mixing and blending of the materials into topsoil mixtures. Standard Industrial Code (SIC) Major Group 14 is allowed in the M zone. (K.C.C. 21A.08.090) Major Group 14 includes peat screening and fill dirt pits, (SIC 1499) The group therefore concluded that topsoil mixing is allowed in the M zone. There were two subsequent RRC decisions from 2000 that, when taken together, would suggest a different conclusion. RRC Minutes 10-27-16 Discussion Topsoil production involves a variety of activities that, when not being done in conjunction with a mine or quarry, are more closely related to industries categorized under Major Group 32: Stone, Clay, Glass, and Concrete Produces. For example, SIC 3295: Minerals and Earth, Ground or Otherwise Treated covers “establishments operating without a mine or quarry and primarily engaged in crushing, grinding, pulverizing, or otherwise preparing clary, ceramic, and refractory minerals; barite; and miscellaneous nonmetallic minerals…” This activity falls under Division D: Manufacturing.

  • Archaeological Investigations of the Mcmartin Preschool Site E. Gary
    McMartin Preschool site Archaeological Investigations of the McMartin Preschool site , Manhattan Beach, California by E. Gary Stickel, Ph.D. Executive Summary BACKGROUND METHOD HYPOTHESES AND TEST EXPECTATIONS Part II FINDINGS CONCLUSIONS SUMMATION Executive Summary During the month of May 1990 an archaeological project was conducted at the McMartin Preschool site to determine, once and for all, whether or not there had ever been tunnels under the building, as described by various children. Excavation was carried out according to established scientific conventions with a careful research design defining what might prove or disprove the existence of "an underground feature that would connect to the surface of the site and extend underground for some distance..(with) dimensions large enough to accomodate adult human movement through it." (p 24) The project unearthed not one but two tunnel complexes as well as previously unrecognized structural features which defied logical explanation. Both tunnel complexes conformed to locations and functional descriptions established by children's reports. One had been described as providing undetected access to an adjacent building on the east. The other provided outside access under the west wall of the building and contained within it an enlarged, cavernous artifact corresponding to children's descriptions of a "secret room". Both the contour signature of the walls and the nature of recovered artifacts indicated that the tunnels had been dug by hand under the concrete slab floor after the construction of the building. Whatever the purpose of this elaborate enterprise, even more effort must have been devoted to filling the tunnels back in and trying to conceal any evidence of their existence.

  • Elevating Your House
    CHAPTER 5 Elevating Your House Introduction One of the most common retrofitting methods is elevating a house to a required or desired Flood Protection Elevation (FPE). When a house is properly elevated, the living area will be above all but the most severe floods (such as the 500-year flood). Several elevation techniques are available. In general, they involve (1) lifting the house and building a new, or extending the existing, foundation below it or (2) leaving the house in place and either building an elevated floor within the house or adding a new upper story. During the elevation process, most frame, masonry veneer, and masonry houses are separated from their foundations, raised on hydraulic jacks, and held by temporary supports while a new or extended foundation is constructed below. The living area is raised and only the foundation remains exposed to flooding. This technique works well for houses originally built on basement, crawlspace, and open foundations. When houses are lifted with this technique, the new or extended foundation can consist of either continuous walls or separate piers, posts, columns, or pilings. Masonry houses are more difficult to lift, primarily because of their design, construction, and weight, but lifting these homes is possible. In fact, numerous contractors throughout the United States regularly perform this work. A variation of this technique is used for frame, masonry veneer, and masonry houses on slab-on-grade foundations. In these houses, the slab forms both the floor of the house and either all or a major part of the foundation. Elevating these houses is easier if the house is left attached to the slab and both are lifted together.
