The Lausanne Tunnel in Jim Thorpe was installed in 1906 to dewater the coal fields in this area. The tunnel discharges about 6000 gal/min of drainage that is relatively high in iron and manganese but fortunately, the pH is relatively high and aluminum content is low. The remediation installed in 2004 was a two part passive wetland system that has been the focus of the conservation efforts by a number of conservation organizations since that time. My involvement has been to engage the local Sierra Club as well, the local trout stocking clubs and other organizations to provide funding and manpower for upgrades at the site. In 2007, two 5ft rectangular weir flow monitors were installed, one in the wetland and the other in the bypass flow, which consists of 2/3rd of the tunnel discharge flow. Pressure transducers and solar powered data loggers were installed to record both flows so that further hydrological engineering could be applied to optimize the wetland treatment while also devising a treatment plan for the bypass flow. In 2011, artesian aerators were added to the feeder pipes to improve aeration of the water entering the wetland. The aerators, however, did consume some of the available head pressure and reduced wetland feed flow so in 2014 a 3rd 14” feeder pipe was excavated and installed bringing the wetland flow rate back to the 1800 gal/min design rate. In 2016, a solar powered compressor was installed with two aerator heads added to the wetland to further boost dissolved oxygen. Iron test kits and dissolved oxygen monitors have been used to evaluate the iron removal effectiveness of the wetland and the extent of oxygen saturation. The next steps at for further improvement are the installation of cascading settling basins in the bypass flow as well as optimization of the wetland flow distribution. This presentation will feature presentation of technical flow and composition data as well as drone video of the site.

In 1991, a drain tunnel used to drain water from a mining pit was sealed with a concrete plug. In 1996, the plug failed and released 1.6 million cubic meters of tailings into the 26-kilometer Boac River. The tunnel was resealed in 1996 and 1997. There was disagreement over how to clean up the river, so no official cleanup plan was approved. However, monitoring showed the river water quality gradually recovering to safe levels. While some tailings remain, studies found they do not significantly impact the environment. Traditional river uses have resumed.
Incorporating the design features that were successful in the treatment capacity of the 1.2 acre wetland at the Flight 93 site for a typical flow = 775 gpm. The average percent removal was roughly 70% for iron and 50% for manganese within the wetland. This analysis allowed for a design foundation of the polishing aerobic wetland at the Clyde Mine Water Water Treatment Facility and the potential application at other mine water treatment locations where a relatively minor amount of polishing is needed to enhance iron and manganese removal for the final discharge.
Woodglen Lake is undergoing a dredging and restoration project to remove 32,500 cubic yards of sediment that has accumulated over the years.

Terry Schmidt, Skelly & Loy, “Big Run Restoration: A Success Story”Michael Hewitt, GISP
In the late 1990’s, a watershed assessment was completed for Blacklegs Creek and its Big Run tributary, which was the first step to development of a restoration plan. Design and construction activities were initiated around 2000. A four phase approach was developed to address the significant acidic pollution contributors in the watershed. Phase 1 consisted of treating “Big Run #2,” aka. the Sporanza discharge. The water was piped about ½ mile under Blacklegs Creek and treated using an open limestone based system. Phase 2 consisted of treating “Big Run #7” also using a limestone based system. Phase 3 was the biggest challenge due to the discharge location, water quality, water flow, and available space. To combat these challenges, a mine seal constructed in a drainage tunnel that effectively raised the water head approximately 30 feet to a location where some space was available. Partial treatment was accomplished using limestone which required frequent mixing to prevent clogging. Phase 4 was constructed to address “Big Run #3” (emanating from a location without property owner coordination) as well as providing for seasonal and supplemental treatment of Big Run #7 and #8. Through numerous grants of all types and 15 years or so of hard work, bugs and fish returned to lower Big Run and Blacklegs Creek below the confluence.

The Lower Lackawanna Watershed near Scranton, PA, is polluted by the largest abandoned mine drain (AMD) in the eastern US. The Old Forge Borehole spews 100 cubic feet per second of iron laden water into the Lackawanna River decimating the aquatic habitat and fish populations for miles downstream and into the Susquehanna River. This assessment was completed in 2012 and the plan recommends cleaning up this discharged and a related discharge, the Duryea Breach, in order to remove approximately 5 tons of iron per day using an active treatment plant. The plant could also have many other beneficial effects besides producing clean water, like hydroelectric power, geothermal heating, iron oxide resource recovery. With these added benefits, the initial ~$15 million investment in a plant could be paid off over and over again.

This document summarizes a community forum discussing a proposed soil reclamation project in Pepperell, MA. The forum covered an overview of the project, which would import up to 3.2 million cubic yards of soil over 7-9 years via 160,000 truckloads. Concerns were raised about the frequency of soil contaminant testing and potential impacts to nearby water resources. Representatives from local advocacy groups expressed opposition, citing problems with other reclamation projects in MA. Attendees were encouraged to engage with local officials and support legal challenges to the proposed project.
The Woodglen Lake Dredging & Restoration project in Fairfax County, VA removed over 40,000 cubic yards of sediment from Woodglen Lake. The project improved maintenance access and installed a sediment forebay to simplify future dredging. Dredged sediment was disposed of innovatively at the County-owned I-95 Landfill Complex. Stream restoration and landscaping around the lake also enhanced the area. The project reduces annual sediment and nutrient loads in downstream waters.
Highway 40 in Alberta was severely damaged by 2013 floods, with over 100 locations along a 55km stretch requiring repairs. The highway provides access to Kananaskis Country and is the highest paved road in Canada. Associated Engineering was tasked with repairing the highway in under 5 months while minimizing environmental impacts. They developed innovative solutions like an environmental monitoring database tool and expedited regulatory approvals. The highway was reopened ahead of schedule in September 2013, restoring access to the area.
Reconsider North Cowichan RCMP detachment 2020Hajo Meijer
I created this presentation for a study assignment. North Cowichan is planning to build a new RCMP facility on the edge of town on a site that is currently a farm field. I believe this is a mistake as the Cowichan Valley is already being spoiled by (sub)urban sprawl. IMO it should be planned within the existing build-up area of Duncan. Sadly, with the current situation around Covid, council is not accepting delegations, so I'm hoping to bring some awareness to the issue in this way.

Tom Gray, Tetra Tech Inc. - “Coal and Coal Mine Wastes a Resource for Rare E...Michael Hewitt, GISP
Coal and coal mine wastes are a potential source of rare earth elements. Samples from coal basins in the United States found concentrations over 300 parts per million of rare earth elements and related elements in 20% of samples. The highest concentrations were found in coal seams and associated strata in Northern Appalachia, especially the Lower Kittanning seam in Pennsylvania. Acid mine drainage treatment sludges from these areas averaged over 1,000 parts per million of rare earth elements. Further characterization and processing research is needed to evaluate the feasibility and economics of extracting rare earth elements from coal and coal byproducts.

Andy Freifeld, Temple University, “Landscape Design and Reuse Planning in Min...Michael Hewitt, GISP
Funding for mine land reclamation is difficult to acquire and, while the environmental benefits of reclamation are fully understood, the economic benefits of reclamation are just beginning to be appreciated. Innovations in landscape design and reuse planning can attract partnerships with lenders and investors and spur the economic development associated with reuse of abandoned mine lands. Strategies like energy development, carbon sequestration, and wetland banking can address environmental concerns, but should also preserve historical and cultural legacies in order to maximize economic gain. These environmental strategies are now being encouraged by State and Federal agencies, while the cultural legacies are more universally overlooked. This presentation will discuss the ways in which environmental design of reclamation projects could benefit both economically and environmentally by the inclusion of preservation and consideration of historical and cultural legacies of the sites, while still utilizing core environmental strategies.

(Q)SAR Assessment Framework: Guidance for Assessing (Q)SAR Models and Predict...hannahthabet
The webinar provided an overview of the new OECD (Q)SAR Assessment Framework for evaluating the scientific validity of (Q)SAR models, predictions, and results from multiple predictions. The QAF provides assessment elements for existing principles for evaluating models, as well as new principles for evaluating predictions and results. In addition to the principles, assessment elements, and guidance for evaluating each element, the QAF includes a checklist for reporting assessments.
This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.
Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

Trichogramma spp. is an efficient egg parasitoids that potentially assist to manage the insect-pests from the field condition by parasiting the host eggs. To mass culture this egg parasitoids effectively, we need to culture another stored grain pest- Rice Meal Moth (Corcyra Cephalonica). After rearing this pest, the eggs of Corcyra will carry the potential Trichogramma spp., which is an Hymenopteran Wasp. The detailed Methodologies of rearing both Corcyra Cephalonica and Trichogramma spp. have described on this ppt.
2. SEANOR GFCC-
A POSITIVE IMPACT
Pennsylvania’s 2014 Abandoned Mine
Reclamation Conference
June 26-27, 2014
State College, PA
Jeff Polenik, Manager - Engineering
3. But first…… A Thank you
• To the 2014 PA Abandoned Mine Reclamation
Conference Committee
• ARIPPA and Congratulations on your 25th Anniversary
• Sponsors for the Conference
4. Who we are
• Robindale Energy Services, Inc. is a western
Pennsylvania company that primarily deals with the
permitting and mining, and transportation of waste coal
from 8 counties in the bituminous coal fields to waste coal
burning plants in the state. Robindale’s operations over
the past 22 years have helped clean miles of streams and
remove millions of gallons of acid mine drainage in
Pennsylvania at no cost to the taxpayers. From 1991
through 2013, Robindale (and its affiliate RNS Services)
has reclaimed over 40,080,744 tons of waste coal and
has completely reclaimed 1,018 acres of abandoned mine
land.
5. Background Information of the
Seanor Site
Located in Loyalhanna Township, Westmoreland County
The Site is approximately two (2) miles southwest of
Saltsburg, PA.
The Loyalhanna Creek basin is the major drainage basin
for the site and is bordered on the west by Getty Run which
meets with Loyalhanna Creek just north of the site. To the
east the site borders Loyalhanna Creek.
7. Prior Site Conditions
The refuse pile, consisting of two (2) main piles and two (2)
smaller piles, was generated from the abandoned Loyal
Mine.
It appears there was a coal tipple and rail load out
associated with the deep mine.
The deep mine complex was situated on the Upper
Freeport coal seam.
9. Project Description
• Located within the Loyalhanna Creek Watershed, the 46.6
acre Seanor site is situated in Loyalhanna Township,
Westmoreland County consisted of approximately 18.6
acres of abandoned refuse piles scattered throughout the
area with little to no vegetation existing. The abandoned
waste coal piles were up to the edge of the stream bank
on a portion of Getty Run and placed nearby Loyalhanna
Creek providing a direct flow path for waste coal and
acidic runoff during precipitation events to enter into the
waters of the Commonwealth. Additional hazards / risks
included steep slopes that pose a threat to hikers and ATV
riders. Also, bisecting the site is a Westmoreland County
owned Rails to Trail pathway that is frequently utilized.
20. Evaluation for Removal Authorization
• Typically have 4 Avenues to pursue
• 1 – Exploration Permit
• 2 - Consent Order and Agreement
• 3 – Surface Mine Permit for Refuse Removal (SMP)
• 4 – Government Financed Construction Contract (GFCC)
• For the Seanor Project, the GFCC was the preferred
choice
21. Why GFCC?
• Typically quicker to receive DEP approval
• Designed for site such as Seanor
• Preparation is less intense / involved
• Allows for quick start up
• Liability is minimized
• Ash Back – (at one time)
• Bond release time is reduced.
22. The Process
• To evaluate the site qualifications, a GFCC Pre-
Application was prepared and submitted to the
Greensburg District Office on 12/26/07
• 1/29/08 – Site meeting with OSM, DEP, BMAR,
Consultant. Result site qualifies.
• 10/7/09 – GFCC application to DEP, with provisions for
beneficial ash placement
• 11/25/09 – DEP notifies Robindale that no ash is
permitted on GFCC’s now and going forward
23. The Process - continued
• 12/18/09 – revisions to remove ash submitted
• Throughout 2010 – caught up in Department shuffle,
notifications, Government shutdown and new fees
• 1/3/2011 – Contract Issued – still not quite ready to go….
• Filed for NPDES Permit through the Westmoreland
County SCS in 1/21/11
• 2/10/11 – SCS Approval received – site is now ready to
activate
24. Summary
• Total time to obtain Contract Approval almost - 3 years
and 2 months
• Other GFCC’s – 12 to 18 months
• For comparison: Length of time to conduct refuse removal
– started 3/3/2011 ended 8/27/12 followed by reclamation.
• Total time – 1 year and 5 months
• Tons of Waste Coal removed – 305,000
30. Destination
Waste Coal was delivered to Seward Power Plant operated
by NRG
Still remains as the largest CFB Power Plant in the country
(515 NMw)
Receives on average 600 loads of waste coal and 120
loads of limestone per day – 5 days per week
Removes on average 580 loads of beneficial ash and
rejects per day – 5 days per week
31. Left Behind
• Not all of the waste coal was considered useable material.
Portions that were not usable remained on site and mixed
with lime and soil like material excavated on-site and
contoured into the proposed final grade for the site.
Typically, traditional topsoil from these sites are limited
and virtually non-existent. As the waste coal is removed to
the original ground, the soil beneath the material is tested
for potential cover material and if results are positive, the
material is stockpiled and utilized for cover material at the
completion of the project. Proper nutrients are added to
the soil during the reclamation process to provide for
successful revegetation.
42. Trail Background
• The Westmoreland Heritage Trail follows the rail bed of
the former Penn Central RR, which fell into disuse in
1972. The rail line was originally opened in 1852 by a
subsidiary of the Pennsylvania Railroad Company, led by
George Westinghouse, Jr. to connect Saltsburg and
Export. Currently the trail travels between Saltsburg and
Slickville, but plans call for a 20 mile trail all the way to
Trafford. The next phase of construction will extend the
trail another 4 miles from Slickville towards Delmont and
is expected to be completed by the Fall of 2013. In
Saltsburg this trail converges with the West Penn Trail at
the Saltsburg Playground.

47. Project Partnerships
• During the active operation of the Seanor GFCC, the site
was monitored monthly by the assigned Mine
Conservation Inspector from the Greensburg District
Office of the Department of Environmental Protection.
During the life of the project, excellent communication
was conducted between Robindale Energy personnel and
the MCI to assure was project was completed as planned
with no environmental incidents occurring during the
operation.
48. Economic Impact
• The estimated cost of the project was determined to be
$250,034. All of which was completed at no cost the
Commonwealth. During the project life, Robindale
employed 3 employees at the site with a combined gross
payroll of $210,000. The waste coal was removed from
the site and transported by truck to the Seward
Generating Station, which yielded a gross income of
$1,586,504 for the various trucking companies contracted
by Robindale Energy throughout the life of the Seanor
GFCC project
49. Environmental Results
• Several positive results occurred upon the completion of
the project. A lush vegetative cover has been established
to improve surface water runoff leading into the nearby
streams. The approximate original contour of the land fits
in well with the existing topography of the surrounding
area. Small game species have been seen throughout the
site feeding on various grasses planted. The individuals
who frequent the trail now have a nice area to pass
through to observe wildlife and discuss the improvements
and enhancements that took place prior to remembering
the area as a barren wasteland it once was.
50. A Nomination for Consideration
• Given all the positive results of the project, Robindale
nominated the site for the Governor's Award for
Environmental Excellence for 2014
51. The Results
• I am pleased to inform you that your organization has
been selected to receive a 2014 Governor’s Award for
Environmental Excellence! Each year, projects that
encourage and promote environmental stewardship are
selected to be recognized at the Pennsylvania
Environmental Council’s Annual Dinner. This year we
