Environmental trends concern suppliers.

Environmental Trends Concern Suppliers

The increasingly stringent environmental regulations confronting U.S. casting producers present the same concerns to those who supply products and materials to foundries. Laws and regulations governing the handling and disposal of solid and hazardous wastes are posing a particularly difficult problem for foundries and suppliers alike.

In adressing the annual meeting of the Casting Industry Suppliers Assn (CISA) on Nov 9-10 in Rosemont, IL, Fred Simonelli, California Cast Metals Assn, told the group that "Many of today's environmental concerns have been created by the demands of society, not necessarily by industries like metalcasting. Unfortunately, the burden of correcting the problems has come down on the shoulders of industry.

"Somehow, all of society, like industry, must share in the responsibility of solving our environmental problems."

In light of the newly published (Nov 22, 1989) EPA land regulations, the biggest task facing foundries and suppliers is disposal of hazardous waste. The proposal forbids disposal of any material in a landfill that fails EPA's hazardous waste testing procedures. This could include materials such as foundry sands, arc furnace dusts or other common foundry materials routinely disposed of in the past.

What makes this regulation particularly onerous is that it comes into full force after May 8, 1990, a date which Simonelli calls "unalterable."

Robert Zayko, RMT, Inc, reiterated Simonelli's message that foundries and suppliers are facing increasing scrutiny in environmental matters. Generally, he said, the major trends in solid and hazardous waste management include increasingly tighter regulatory control and scrutiny by the public and the media, the growing scarcity of suitable disposal sites and the dramatically rising cost of disposal.

What makes a foundry material hazardous? According to Zayko, generally any material that meets one or more of the following characteristics may cause it to be classified as hazardous:

* Ignitable--has a flashpoint of less than 140F;

* Corrosive--pH factor is less than 2.0 or greater than 12.5;

* Reactive--reacts violently with water to form toxic fumes or creates a potentially explosive mixture when mixed with water;

* EP Toxic--contains heavy metals such as lead or cadmium.

Zayko offered several examples of foundry processes that may generate hazardous wastes. In the melting area, calcium carbide in slag from desulfurization may be reactive, and melting materials which contain heavy metals could prove to be EP Toxic. From brass and bronze foundries, molding sand systems where the castings contain lead could test EP Toxic. In some cases, debris from core system scrubbers for off gases may be characterized as corrosive.

Air toxics is another area of regulatory action that will affect foundries and their suppliers, according to Zayko. "Scrap suppliers," he said, "many be required to supply presorted scrap to eliminate hazardous wastes that may be delivered to foundries. Sand suppliers may have to develop their own landfills for waste sand or build central reclamation systems.

"The gist of the air toxics regulation involves the quality of air that goes beyond the property line of your plant. It's a new area of regulation altogether."

CISA Business

Along with presentations on environmental regulations, CISA also conducted official business during its annual meeting, including the election of new officers.

The new CISA president for 1989-90 is Jerry Agin, vice president/general sales manager, Hill & Griffith Co. Vice president of the CISA equipment division is Joseph Post, president, Roberts Corp. Chuck Fowler, president, Wedron Silica Co, was elected vice president of the supply group.

In his final address as CISA president, Lou Pedicini reported that the organization's membership stands at 62 companies, up ten from a year ago. He also introduced the group's newly elected directors: Bruce Dienst, National Engineering Co; Dan AuBuchon, M.A. Bell Co; Bill McKillip, QO Chemicals, Inc; Rick Smith, Foundry Div/Ashland Chemical Co; and Jervis Webb, Jervis B. Webb Co.
