SEEKING SOLUTIONS Our collective footprint as humans has disturbed native landscapes and underlying soils. Heavy equipment used in construction can compact soils. Mining can result in loss of topsoil. Overgrazing disturbs native vegetation and wind and water erosion occurs when ecosystems are disturbed. Following this damage, soils are often unable to support plant life due to lack of nutrients and organic matter, compaction, altered pH and other ecosystem changes. BENEFITS OF BIOSOLIDS Disturbed soils can be restored and revitalized Before and after a reclamation with biosolids through the addition of organic matter. Nutrient-rich, organic biosolids replace lost can access over time. Soil, following biosolids topsoil and improve soil fertility and stability, application is better aerated and lighter.

    Report on Abandoned Mine Land Reclamation Economic Development Pilot Program (AML Pilot Program) for FY 2016 – FY 2017 Prepared by the Office of Surface Mining Reclamation and Enforcement (OSMRE) Prepared by the OSMRE Program Support Directorate March 28, 2017 Page 1 of 18 I. Introduction and Background The Abandoned Mine Land Reclamation Economic Development Pilot Program (AML Pilot) for FY 2016 was authorized by Congress under the Consolidated Appropriations Act, 2016 (Public Law 114-113) and enacted on December 18, 2015. Administered by the Office of Surface Mining Reclamation and Enforcement (OSMRE), the AML Pilot provided $30 million of US Treasury Funds to each of the three Appalachian state AML Programs (Kentucky, Pennsylvania and West Virginia) which have the highest amount of unfunded coal-related problems that are classified as Priority 1 and Priority 2 abandoned mine lands sites and inventoried in the Enhanced Abandoned Mine Land Inventory System (e-AMLIS). The AML Pilot funds are to be used “for the reclamation of abandoned mine lands in conjunction with economic and community development and reuse goals”. This report describes implementation actions for the AML Pilot. II. Implementation of the AML Pilot Program OSMRE facilitated a meeting on February 24, 2016, in West Virginia with state AML Program staff from Kentucky, Pennsylvania and West Virginia to obtain input on the implementation on the AML Pilot Program. A second meeting was held on March 16, 2016, in Lexington, Kentucky to solicit input from additional stakeholders on the AML Pilot. OSMRE also participated in workshops with economic development organizations convened by the Appalachian Regional Commission (ARC) in the three states to provide information about the AML Pilot Program and to encourage state and local economic developers to identify opportunities to align and leverage their efforts with AML reclamation projects.

  • South Palo Alto Tunnel with At-Grade Freight
    RAIL FACT SHEETS South Palo Alto Tunnel with At-Grade Freight About the Tunnel with At-Grade Freight For the tunnel alternative, the railroad tracks will be lowered in a trench south of Oregon Expressway to approximately Loma Verde Avenue. The twin bore tunnel will begin near Loma Verde Avenue and extend to just south of Charleston Road. The railroad tracks will then be raised in trench to approximately Ferne Avenue. The new electrified southbound railroad tracks will be built at the same horizontal location as the existing railroad track, however, the northbound track will be moved to the east within the limits of the tunnel to accommodate the spacing required between the twin bores. The railroad tracks in the trench and tunnel will carry only passenger trains. The freight trains will remain at-grade. The roadways at Meadow Drive and Charleston Road remain at their existing grade and will have a similar configuration that exists today with the addition of Class II buffered bike lanes on Charleston Road. This will require expanding the width of the road to maintain bike lanes through the overpass of the railroad. By the numbers Neighborhood Considerations • Diameter of twin bores is 30 feet. • Alma Street will permanently be reduced to one lane • Railroad track is designed for 110 mph. in each direction from south of Oregon Expressway to Ventura Avenue and from Charleston Road to Ferne • Meadow Drive and Charleston Road are Avenue. designed for 25 mph. • The train tracks will be approximately 70 feet below the Proposed Ground Level View - Looking Southwest • Maximum grade on railroad is 2%.

The infrastructure will close a major gap in the project across the European transport network, reduce the risk of Fehmarnbelt. shipping collisions, energy consumption and create a new region in Europe, while also fostering the development of new nature and recreational landscapes by Working with Nature concepts. Presentation of the project The Fehmarnbelt Fixed Link – the proposed eastern route between Germany and Denmark – has been planned for a long time in an effort to create a rapid connection between the two countries with a faster and shorter link (see Figure 1). It will also close a major gap in the Scandinavian-Mediterranean corridor which is part of the European transport network. Once opened, the journey for freight trains between Hamburg and Scandinavia will reduce by 160 kilometres. The Fehmarnbelt Fixed Link is a joint Danish and German transport infrastructure project across the Fehmarnbelt. Denmark is responsible for the planning, construction and operation of the Fehmarn Fixed Link. To carry out this task, the government of Denmark has established the company Femern A/S which is 100% owned by the Danish State and represented by the Danish Ministry of Transport.

  • Utilization of Locally Available Organic Matter to Improve Chemical Properties of Pyroclastic Materials from Mt

Kelud of East Java S.R. Utami*, C. Agustina, K.S. Wicaksono, B.D. Prasojo, H. Hanifa Faculty of Agriculture, University of Brawijaya, Jl. Veteran 1, Malang 65145, Indonesia *corresponding author: [email protected] Abstract: Pandansari village, Ngantang District was severely affected by Mt. Kelud eruption in 2014. Almost all soil surfaces were covered by the eruption product, leading to serious problems for cultivation. Pyroclastic materials potentially have high content of nutrients, but they are not readily available to plants. As an attempt to improve chemical properties of the pyroclastic materials, we applied locally available organic matters, from four different sources, i.e. leaves of sweet potatoes, Tithonia diversifolia, maize, and cow manure. The pyroclastic materials were sieved at 2 mm, placed inside pots (50 x 50 x 50 cm3), until it reached 30 cm thick. The fresh leaves were chopped into 2 mm size and mixed with the pyroclastic materials at the dosage of 15 Mg/ha. They were incubated and kept at field condition. Selected chemical properties (pH, CEC, sum of basic cations, and the total contents of N, organic C, and available P) were measured before and after 90 days incubation. The results showed that after 90 days, organic matter application significantly increased pH, cation exchange capacity, organic C, and total exchangeable basic cations content.
