Green infrastructure policy for stormwater infiltrationEvan Pratt
Viewers will get an overview of policy changes to require infiltration as a strategy to address stormwater quality and quantity in Washtenaw County, along with a link to a wide range of resources including the 150+ page regulations and case studies that show cost savings for greenfield developments. Design storms have increased nearly 20% in volume in the past 30 years in the target area, so existing infrastructure no longer meets the needs it was designed for. Older infrastructure was already overwhelmed.
Effective water management is critical to both open-pit and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively managed dewatering processes typically employ continuous water level monitoring.
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.

Effective passive minewater treatment systems can be attractive to the public because they do not contain hazardous components, support wildlife, and communicate a resonating message of frugal ingenuity. This talk will focus on two passive treatment systems in Allegheny County that have become central components of popular public spaces: Allegheny Land Trust’s Wingfield Pines system and Pittsburgh Botanic Garden’s Woodlands system. The presentation will be supported with photos and statistics regarding the public use of both systems.

This study investigates the procedure for removing contaminants from rivers and streams that were left as a result of Acid Mine Drainage. The understanding of the process is used to investigate possible goods and services that may result from the process, and the marketability of the goods and services as potential sources of revenue. Taking into account the potential revenues sources, a business plan is created to describe how an entity in the “industry” of Acid Mine Drainage Recovery would operate. The business plan takes advantage of cost accounting techniques to better compare the costs incurred by the business against the potential revenues gained, resulting in cost-benefit analysis.
Because of the extent of AMD impacts in Pennsylvania, the Commonwealth has become, by necessity, a leader in the development of passive treatment technology. People from around the world travel to Pennsylvania to learn about the successes we have collectively achieved, including the installation of over 300 passive treatment systems. In recent years, the capabilities of passive systems to treat highly acidic mine discharges with high concentrations of dissolved metals has been questioned. It is important to remember that with any treatment system, whether passive or active, proper design, suitable land characteristics, quality construction, proper maintenance and sufficient funding, are needed to provide a long-term, cost-effective approach for watershed restoration. This presentation will provide mini case studies that demonstrate, by example, that passive systems can and are effectively treating acidic, high-metal, discharges in Pennsylvania.
At 300 meters depth, we have it covered. But at depths up to 3000
meters, the physical conditions demand a radical re-think around
techniques and technology.

Managing Stormwater in the Hudson Valley: A Cost-Benefit Analysis of Permeabl...Libby Zemaitis
Stormwater management is a priority in New York State that is gaining attention due to increased intense precipitation from climate change and increased urban development. The state has adopted stricter regulations that are driving the adoption of green infrastructure. Municipalities, schools, and private firms are already installing permeable pavement in the Hudson Valley, but there is a lack of robust, unbiased economic analyses of the technology found in the peer-reviewed literature. This thesis uses existing models and empirical studies to create a cost-benefit analysis model for permeable pavement in the Hudson Valley. The model estimates the five primary costs and benefits of permeable pavement as outlined in the literature: installation cost, operating and maintenance cost, runoff reduction benefit, pollutant removal benefit, and deicing reduction benefit. The initial analysis of a hypothetical one-acre permeable parking lot yielded a significant positive net present value. Despite various weaknesses, this model is a significant improvement on previous models in a new amalgam of more singular and unbiased studies of permeable pavement. Future work could include a transformation of this model into user-friendly online tool for prospective adopters to better understand the balance of costs and benefits of permeable pavement in the Hudson Valley and beyond.

Russian anarchist and anti-war movement in the third year of full-scale warAntti Rautiainen
Anarchist group ANA Regensburg hosted my online-presentation on 16th of May 2024, in which I discussed tactics of anti-war activism in Russia, and reasons why the anti-war movement has not been able to make an impact to change the course of events yet. Cases of anarchists repressed for anti-war activities are presented, as well as strategies of support for political prisoners, and modest successes in supporting their struggles.

process through which consultants, businesses and organizations can
request an agency review of a proposed strategy. Proposals receiving a
favorable review will be included in a library of accepted technologies
that will be published on the Department's website. It should be noted
that Departmental acceptance suggests that Agency experts believe a
