I was pleased to find quick transportation to one of the premier locations in the region, the “Ciragan Palace, Kempinski to attend the Caspian Forum 2013. A quick shower, dawned a suit and down to meet my sponsors that invited me. David Zarebinski and Ziya Gaziyev of DZG Group “Berlin”. Mr. Zarebinski and Mr. Gaziyev were shaking hands and walking me right into the center of much commerce, discussion and opportunity.
I was fortunate to be present and honored to meet many ministers, politicians, parliament members, advocates and business representatives in this unique European / Asian Region of the World. We are seeking business opportunities in Turkey, Azerbaijan, and in the surrounding region.
The Caspian Forum is a platform that explores the economic, political, and strategic potential of the Caspian Region, while defining areas of collaboration and partnership with the spirit of the win-win principle. The Forum brings influential voices of the academic, business and policy world together to lay foundations for a prosperous, secure and democratic region. It enhances opportunities for positive neighborly relations, facilitates mechanisms for regional integration and encourages constructive international involvement. It aims to create a space for multilateral cooperation and to avoid geopolitical rivalry. The Forum is a unique setting to promote a shared vision on the issues of security, economy and energy of the Broader Caspian Region. The Forum designs its agenda with a priority of developing a comprehensive approach in addressing outstanding problems of the region.

January 16, 2012 – NIAGARA WISCONSIN (For Immediate Release)
NIAGARA DEVELOPMENT COMMITS TO A 2012 FACE LIFT
Niagara Development is quickly approaching its February 11th one year anniversary as owner of the former NewPage Paper Mill in Niagara Wisconsin and operator of the 1,300 acre property conversion that straddles the Menominee River in both Dickinson and Marinette Counties.
After exhaustive research and on site review from industry experts and business redevelopment teams from around the region, it has become clear that many of the “purpose built” structures on the site were not an advantage to new comers, but as stated by most suitors, a deterrent to utilization and restoration. “NIAGARA has engaged real estate and construction professionals alike to walk the vacant buildings that were used for the manufacturing of ‘Paper’, ‘Pulp’ and ‘Power’ in order to outline options that fit the areas reuse plan. Every response focused on the difficulty of conversion to standard industrial use,” says President of NIAGARA Development, Eric J Spirtas. “Every professional sees the immediate value in the; Shipping, Coating and Warehouse buildings, but highlights a ‘disconnect’ when considering the reuse of the remaining large multi-story industrial buildings.”
Recently a National firm contacted NIAGARA Development, offering to buy all of the structures and associated equipment at the facility to “Demolish and Scrape” the entire site, creating a cleared brownfield parcel. This proposal did not fit NIAGARA Development’s desire or intent. Instead NIAGARA Development took this opportunity to strategically plan the retention of the most marketable buildings, while accepting parts of the original proposition, which will result in the removal of the un-usable buildings. This work will start immediately and will open up the remainder of the site for re-purposing of any type. “Removing the unsuitable buildings will provide NIAGARA with a unique opportunity to market available space to any type of company and then specifically design buildings and usage patterns that fit the needs of today’s buyer,” says Spirtas.
The company removing the unusable structures will also spend a significant amount of money getting the railroad back in full operation giving NIAGARA Development a distinct advantage in marketing the property to new businesses. “Bringing in upgraded rail will be a benefit to the mill property’s long-term redevelopment plans providing greater value to the remaining buildings,” says Niagara Mayor, George Bousley. “Rail will be rebuilt from Kimberly Road to the mill site.”
“The Niagara facility offers some exceptional opportunities in Northeast Wisconsin for manufacturing and warehousing/distribution,” according to Tom Scheuerman, CPA, and managing broker of Grubb & Ellis|Pfefferle in Appleton, WI. “From our vantage point, the repositioning and reuse of a former manufacturing facility like in Niagara offers great advantages for both companies looking for affordable space with excellent attributes and local communities with outstanding ready work forces. In order to attract new business into an area, we have seen that facilities like Niagara are critical to that process because they are on-line and ready for occupancy. This facility offers some exceptional manufacturing space, low-cost power, waste water treatment, expansion capability, rail service and hundreds of acres of land that can be very attractive to new businesses.”
Spirtas continues to show his commitment to the local area by setting up his corporate headquarters known as NIAGARA Worldwide at the Mill. He will be using the former Clubhouse building as his main offices. Extensive renovations are underway in that structure right now for occupancy in the next few weeks. NIAGARA Worldwide specializes in services ranging from; Acquisitions, Consulting, Contracting, Development, Mining, Liquidation, and Trading. Niagara Worldwide is NIAGARA Development’s first tenant setting up its operation in the notable Clubhouse building.
“The NewPage Niagara Mill redevelopment team named the Upper Menominee River Area Alliance (UMRAA), including New North, Inc., continues to focus on repurposing the mill site,” said Jerry Murphy, Executive Director of New North, Inc., the economic development organization of the 18-county region of Northeast Wisconsin, known as the New North region. “The Redevelopment team looks forward to continuing to work with NIAGARA Worldwide to market the existing mill site for future use.”
“The current ownership of Niagara is optimizing the site and removing old buildings that are functionally obsolete and a deterrent to future use and development. This will enhance the site and allow for expansion capability around the structures that are usable for manufacturing and warehousing. This approach of preparing sites and redevelopment of the facilities offers the greatest opportunity to attract new business. We have seen this formula work successfully in other communities,” says Scheuerman.

ADDITIONAL “CLUB HOUSE” HISTORY AND INFORMATION:
The first Club House was built in the year 1907 with the formal opening early in 1908. The original building included a soda fountain, a small ice cream parlor, poolroom, shower and locker rooms, bowling alleys, and the gymnasium, which served alternately as gymnasium and theater. A second floor housed the library, a dining room and kitchen, and rooms rented by the Masonic Lodge. The Club House was rebuilt in 1926, with only the gymnasium of the original building remaining. The bowling alleys were moved to the west side of the building, the ice cream parlor was enlarged as was the soda fountain, and the large lobby was constructed and furnished. In addition, the second floor at that time had a modern kitchen, dining room: a Women’s Club Room, and lodge Rooms.
The Papermill Workers’Unionmaintains an office there. The Skating Club used the Club facilities for planning their Annual Ice Review. The second floor housed the Village Offices, and there was a Village Board Room. The Post Office was located in the northeast corner of the first floor, and the Girls Scouts maintain a room on the second floor for their meetings. The Niagara Community Club remained a truly “community” affair, for few activities of theNiagaravillage came into being without the Club playing some part.

The Niagara Paper Mill was purchased by Niagara Development LLC, who plans to use the mill to attract national business to the area
The former Niagara Paper Mill is under new ownership and looking to bring in business Read more: Local, Economy, Business, Niagara Paper Mill, Niagara Mill Sold, Niagara Development LLC, Niagara, Paper Mill Sold, Paper Mill Purchase
NIAGARA, WI — UPDATE 5:45 p.m.
We know one thing for sure about the former Niagara Paper Mill…it won’t be a paper mill anymore.
The newly formed Niagara Development LLC officially bought the mill from NewPage last week and is planning on using the property and its assets to attract national companies.
“I’m contacted everyday by a new venture or a representative of ventures that are interested in talking,” said Niagara Development President Eric Spirtas.
Spirtas said power and green energy companies are being targeted, given the equipment and assets available on site.
For Niagara Mayor George Bousley, this is a step in the right direction for the area.
“We’re a community of many small communities, so I guess the thing is I’ve watched this economy grow locally,” said Mayor Bousley. “Now if we can bring this part back to the local economy, it means that it’s something you can pass onto the next generation.”
While Niagara is still feeling the effects of the mill closing back in 2008, the town’s resilient attitude has Spirtas confident about the future.
“They have the heart and desire to rebuild,” he said. “Not every town has that, but Niagara does have that. So we look at it as a great hotbed of development.”
Niagara Development is a private company started by Spirtas and another partner for the purpose of developing the site and bringing businesses to the area. The company’s headquarters will be in Niagara, however, the partners have no ties to the area.
Also, no information is being released about the finances of the deal between Niagara Development and NewPage.
An official announcement was made on Tuesday about the Niagara Paper Mill being purchased by Niagara Development LLC. What happens now that the mill has been purchased?
Eric Spirtas, Niagara Development’s president, said that the mill will be used to attract national businesses. The paper mill and land will be sold, in portions, to different companies.
Niagara City Mayor George Bousley said that it will take three to five years for the full impact of the Niagara mill purchase to be felt by the community.

The recent purchase of a complete WOOD ROOM and PGW “Pressurized Ground Wood” System has presented an abundance of available equipment.
PGW Fiber Department
Pressurized groundwood (PGW) fiber is the primary source of fiber used for producing coated groundwood paper.
Woodyard and Woodroom
Local aspen wood was formerly delivered by truck to an on-site 7 area Woodyard that has the capacity to hold 20,000 cords of wood. The wood was then processed in the Woodroom (building 113) where it was debarked and cut into 4 foot lengths at a rate of 19 cords per hour. A delivery system processed and fed the resulting bark and wood waste to the boilerhouse where it was burned as fuel.
The shortened and debarked lengths of aspen from the Woodroom were conveyed to the pulpmill 100 cord capacity storage bin for storage (building 101). The wood was then fed to the main Pulmill’s (building 100) four 7000 hp pressurized grinders where it’s ground to pulp at a rate of 280 tons per day (70 tpd per grinder). Next, the pulp was thickened and pumped to the screening and bleaching area located near the paper machines
PGW Screenroom and Bleach Plant
Final PGW fiber processing was accomplished in the Screenroom (building 95) and Bleach Plant (building 15), both were located in the main mill area near the paper machines. Here the pulp was screened through numerous very fine slotted screens where only the proper size fibers were accepted for making paper. The rejected fibers were thickened and refined down to a more acceptable size before being screened again. The final low brightness screened pulp was then pumped to the bleach plant where it was bleached using a two stage alkaline peroxide bleaching process that both brightened and improved the pulps’ strength properties.
