T or older, the impact will be costly.HCFC-22, better known as R-22, isthe most common Class II substancein use today both residentially andcommercially for air-conditioning andrefrigeration systems. As we approach2020 and the amount of virgin R-22becomes scarce, the cost will rise significantly from an already elevatedpricing structure.

As your older system nears its usefullife span of 12-15 years, repairs involvingrefrigerant leaks or compressor failureswill be very expensive. A monetarysavings plan is recommended over thenext few years as a planned replace-ment approach is more paletable andcost effective than an emergencyreplacement of your air-conditioningsystem. Upgrading to an Energy Star-qualified, high efficiency system thatuses an environmentally friendlyrefrigerant is in your immediate future.

he Montreal Protocol is an international treaty signed by 197

countries worldwide with the sole intenton protecting the Earth’s StratosphericOzone Layer by eliminating the production and consumption of ozonedepleting substances. Within theUnited States, ozone depleting substances (ODS) are regulated ascontrolled substances. Class I substances have a higher ozone depletion potential and to date havebeen nearly completely phased out.Class II substances are all Hydrochlo-rofluorocarbons (HCFCs), which aretransitional substances for many ClassI substances. By 2020 new productionand importing of most HCFCs will bepermanently stopped.

So what’s the consequence for the U.S.homeowner or commercial buildingowner? Well, if your air-conditioningor refrigeration equipment is 10 years

Something Fishy in the Hudson Valley At least in rivers, streams and lakes.

Fish are jumping in Lower Hudson Valley streams, and theUpper Esopus Creek is home to one of the largest populationsof wild rainbow trout east of The Rockies. Another local troutstream stocked yearly by the Department of EnvironmentalConservation is the West Branch Croton River led from the

Croton Falls ReservoirOutlet located in thePutnam County town ofCarmel and theWestchester County townof Somers. The season lastsfrom April 1 throughSeptember 30, and sincethe implementation of “Nokill” regulations in 1995,this stream has become verypopular with anglers who flyfish as the growth of stockedtrout, as well as a fairly significant population of

wild brown trout, is very good.

Streams lead to lakes where the fishing is fabulous as well.Lake Gleneida in Carmel is generously stocked every springwith brown, rainbow, and lake trout, which can surpass sixpounds. The heart-shaped lake is a favorite with anglers; aquiet paradise just minutes from downtown where there areplenty of restaurants for a “bite” to eat when the day is over.Catch and release is the style at Ward Pound Ridge Reservationin Cross River, which is open year round. Anglers of all agesrave about this great fishing spot, and there’s also a dedicatedfly fishing area. Across the Hudson River, over three miles ofpaved path around Rockland Lake in Valley Cottage give easyaccess to anglers. Just twenty miles from Manhattan, you canlaunch your boat from the dock and fish for bass, perch, andthe exotic sounding norlunge. Picnic tables and grills are nearby, making it easy to camp out and cast the whole day.

Spring is in the air, so grab your license, rod and tackle box,and head to one of the many Lower Hudson Valley sweet spotsto reel in some big ones.

The 2016 Summer Olympic Games in Rio de Janeiro inAugust are fast approaching. Olympic athletes are traininghard and making sure their equipment and clothing is worthyof a medal performance.

Science and technology continue to improve the clothes andperformance gear worn by all Olympic athletes, winter or summer. All Olympic-caliber suits start in the lab with syntheticpolymer materials and molecules called monomers. Chemicalengineers decide which monomers to use and how to connectthem to make different materials for different uses. Spandex islightweight and flexible for suits, while Kevlar is strong, yetlightweight for skis and helmets. Even wind resistance can beengineered into a clothing design. Sometimes, a rougher surface can have a lower drag coefficient than a smooth surface, helping an athlete go faster. In sliding sports andspeed skating, a sleek fit can be right for the correct airflow.

In the 2004 summer games, Olympic swimmer Michael Phelpswore a sleek new suit created by Speedo called FastSkin2,which enabled water to move faster over its surface andenhance his performance. He became the first swimmer to win

eight medals in one Olympic Games. Speedo has createdFastSkin3 since then.

Sometimes it’s the look of the uniform as well as the technologythat helps in the athlete’s performance, especially when ajudges’ opinion matters. The flashy USA gymnasts’ uniformswere designed and made byUnder Armour with newtechnology that includesstrategic compression, helping increase blood flow as well as four-waystretch fabrication allowing for greater mobility. Ultimately, ofcourse, it’s exceptional athletes who win themedals and break records,but be aware of whatthey’re wearing when ithappens.

Ever wonder why that one home in your neighborhood hasthe best lawn? A proper watering program from spring to fallespecially during elevated temperature periods is crucial for alawn like theirs. To look its best, your lawn needs the properamount of water each week—but how much and how often?Following these few, easy steps will reward you with a happyand healthy lawn that all the neighbors will be jealous of.

• Maintain 1-1½" of water with three 30-minute wateringperiods per week. You can buy a rain gauge to ensure the properwatering is being achieved or use a simple tuna can. Place thetuna can on your lawn in the watering path and confirm thelevel gathered within a 30 minute cycle. If you are gatheringabout ½" of water per watering cycle, you are on track.

• Early morning watering will ensure that your lawn is notwater logged during night fall, which is important because thiscan introduce fungus and disease problems.

• Use the “Screwdriver Test” as a quick way to determine ifyour lawn is too wet or too dry. Take a 6"-long screw driverand press it firmly into your lawn. If you can easily press thescrewdriver in to the handle, then your lawn is too wet, and ifit will not travel the full 6", it’s not wet enough.

• Install an automatic sprinkler system. This is the easiest methodof having a lush green lawn as the system is programmable tomeet the 1-1½" per week amount. Periodic inspection andmaintenance of the system to verify that there are no brokenor incorrectly positioned spray heads will ensure sprinkler system efficiency and water conservation.

Their Grass Shouldn’t be Greener Make your lawn the envy of the neighborhood.

Technology + Clothing = Gold Of course, years of hard work also helps!
